One doesn't really have to be afraid that every random person in Mexico has a handgun. Violence in Mexico, for the most part,  is very much drug related, for which the demand comes from....the USA. 

It's not "a matter of who you ask." That is RIDICULOUS. The fact is that gun control works, the world over, the evidence is overwhelming, and pretending that there's some sort of nuance to the fact that spraying guns all over a populace results in a lot of gun violence is seriously deranged.
