Dude seriously? You're making a huge leap from what I said to Columbine, OKC, etc...which BTW when was the last time you heard of a mass shooting in The DR?...but that's a different topic altogether.
What I said was that the reason you see what people in this board are calling ghetto behavior has a lot do with the fact that Dominicans are now more likely to see US culture (via Cable TV) and returning Dominicanyork than 20 years ago for instance..."American pop culture" is probably The US greatest export and whether we like it or not the youth around the globe who watch US cable want to imitate American "ghetto" culture.
Note that you need to make a distinction between what people are calling ghetto here (equate to "trashy" dressing an hood rat behavior) vs. your example of destructive behavior (murdering, robbing, etc). Ghetto behavior in this context, at least the way I understand it's being used here, means wearing your pants falling off your @ss, getting those ugly tattoos of marijuana leaves, getting your "grill", "smoking trees" or Hookah for that matter, etc...and yes those "fashions" have all originated or made popular in the "ghettos" of the USA and youth from other countries or the burbs are just following suit. It has nothing to do with violent behavior per se, but a lot of older people associate the two because often times they DO go hand in hand.
