I saw the speech. Basically she's talking about deporting people who have been arrested for a non-violent crime and have irregular status. Instead of giving them a trial, they are deported and banned for 15 years. She also said should they come back, they'd have to go to trial for their crimes.
On the surface it seems reasonable enough - come into the country and break our laws and we'll kick you out - but who knows how it may be put in practice or abused. I don't believe she was referring to 'tourists', but rather foreigners from neighboring countries -- her critics say that people come to rob in Argentina because the laws are more lax here - it seems she wants to address that criticism (same for the penalties for judges for not fulfilling their duties in a timely matter)... how of if it will work in practice is another matter.
If I heard right she also mentioned that in violent crimes, the accused will be incarcerated from the first day until trial, and that the trial should begin no later than 10 months. I believe that was the reference to the moto chorro, but I'm not sure - I would have to listen to the speech again, since I only caught the end.
