That's for the United States.
Brazil is SUCH an unpredictable country. One state can be middle-class neighborhoods and good schools while just an hour away elsewhere, it's anarchical. I'm not against them per se. As someone who generally is distrustful of people, I'm more of an "eh". If you're not a proven terrorist, have at it.
Of course I would like to have an AR-15. Who wouldn't?
Let me just clarify that it is correct that there are many places that are nice neighborhoods with nice schools. Ok. If you watched that play list, you would you notice that the majority of crimes and murders happened in Vila Velha, the nicest place in my state. Don't be mistaken. The criminals know where to go. The neighborhoods that were no too poor or too rich did not have much of a problem.
Watch this video and tell me if you think that I might need an AR-15. This was recorded today from Serra, ES, the neighborhood I pass through to get to Mass or the airport. Brazilians have taken it upon themselves to report, and sometimes those reports are coming from the criminals themselves.
Viewer discretion is advised.
