HGQ - I truly prefer experience more than I do the words of others. Optimistic or pessimistic.
It doesn't have to be my personal experience, but rather, results of things that happen to people I know personally, and that I can see evidence of, or have an implicit trust of those who are doing the reporting of personal experiences. Proof often helps in any case.
Like my older sister-in-law coming over crying because she just got robbed at knife-point for the 5th time, this time as she was going to RapiPago to pay her bills for the month. Or that she comes to our apartment to sleep now when she has to work real late (she's a chef) instead of going all the way to her apartment because two nights in a row recently she was hassled by the same three guys who were threatening to take her into a privado nearby and gang-rape her. Three nights ago, the second time, they chased her a short distance as she screamed and ran around the block and made it to a 24-hour kiosko that was open and had a couple of people standing outside chatting with clerk.
Or my brother-in-law who came over shaking and white one night, lifted his shirt and showed us where a couple of thieves, dressed in suits, stuck a knife in his ribs and stole his cellphone, Sube card and the little bit of money he had on him. Cut him pretty good. Shirt ruined with a hole and blood. He's been robbed multiple times as well, but that was the first time he had any actual injuries.
Both of those happened near Micro Centro.
Or the after-effects (bruising and swelling) that my older sister-in-law's best friend, who is also a chef and works with her, that I saw when she came over with my sister-in-law two days after her and her folks were assaulted in their own home by entraderos, beaten, tied up, and watched while the thieves took what they wanted and broke up a lot of the rest. This was in Flores.
Or a friend of mine who was walking down Callao wearing a nice watch (not brilliant, of course) in the middle of the day and got the watch ripped off his wrist by a couple of motochorros passing by, giving him a pretty good cut in the process.
Or an elder lady, maybe 70 years old, waking down Uruguay, approaching Paraguay, who had the purse ripped off her shoulder by a pair of motochorros who didn't even bother to slow down. The poor old lady literally was spun around two times by the force of the robbery and fell to the sidewalk, hitting her head on the pavement. Quit a bit of blood - head wounds bleed like the devil. I saw that one myself and was one of the many people who rushed to her to help.
Or the bruises on wrist arms and face that one of my wife's cousins showed us after claiming it was caused by a taxi driver in the wee hours one morning as he tried to rape her, telling her he didn't want her money for payment of the fare.
Or the 8 or so kids I saw under my balcony, lined up against the wall of our building by the police, guns and knives laid out in evidence bags on the back of a police cruiser. They sat there for a few hours and I thought the police were waiting for transport to take the gang to jail, but no - they were waiting for their parents to come pick them up, I found out later from our portero.
These are just some of the worst things I've seen or had knowledge of that I consider confirmed to me. There are countless stories from my family and friends of getting wallets, purses and personal items stolen on buses and subte and other places.
I know personally a cop who was a crime scene investigator and is now semi-retired, who toward the end of last year was stabbed repeatedly in the stomach and slashed in the throat by his neighbor, a kid who got pissed off because my buddy asked him to turn the music on his radio (he was listening to out front very loudly). Yeah, that can happen anywhere too, but my buddy has some serious stories to tell about police corruption and what often really goes on with the federal police in Argentina (well, BA at least).
You can go on about how the US is so dangerous, that's fine, you're entitled to your own opinion. You can show data that has been compiled by entities outside of this country that show that Buenos Aires is one of the safest places in South America (while I still don't understand how that makes it even safer than the US in general - unless you REALLY trust the numbers given out by most government in South America more than you do the US, but that's something you have to decide for yourself), but I have to ask to begin with where the entities that compiled that data got their numbers - did they come here and do their own survey and experience how life is, or did they use the numbers the government puts out?
At any rate, I really don't care. I've lived here continuously for more than 6 years. I've made 4 trips back to the States, but the last one was almost 5 years ago. I have never had a single robbery or plain assault perpetrated on myself (well, I was once assaulted by an idiot who ran into my car with his own and then tried to blame me for it, but that could happen anywhere, I'll grant you) in the time I've been here.
But I can't discard the facts that I've seen. Most of the incidents I've listed above took place in the last 18 months. Only one (the watch on Callao) took place a little over two years ago.
My life experience shows me BA is getting more dangerous. Even though, personally, I haven't really been hit by any of it.
My experience in the States? Mostly Texas as far as living goes, by I'm very widely traveled (both in the States and internationally). Living in various parts of Texas, including nice areas and downright slums. I've never seen even a small percentage of the crime I've seen here, over 40-some years, including direct personal experience or known occurrences of friends.
Of course, feel free to roam the streets of BA on those occasions you visit here, dressed in any manner you desire, carrying whatever expensive items with you that you may feel comfortable with. I don't want to see anything bad happen to anyone, but I can't help but think naivete gets an awful lot of people into trouble. Just a matter of time.
And by all means, take all of the precautions that most of us would take here, when you're in the States.
To each their own
Oh yeah - and it's hard to prove a negative (or lack of personal incidents in this case) by example - much easier to prove by the existence of incidents by example.
