I don't think they were implying that it's easy for a normal person to become a criminal, but rather that the people who get into gang life are, in a way, toughened by the fact that they grew up around gang violence. They're beyond fucked mentally by the time they join the gang. These are people who aren't scared to kill. They may regret their lifestyles, but find it too hard to get out. It's easier to just keep on doing armed robberies and murders.

Whereas ICE may be fascists, but how many of them have been in deadly firefights before? How many of them heard bullets whizzing by at the age of 3?

I, too, think ICE would pussy out of a fight against actual gangbangers.

Implying that Somali pirates are Bad People who were always destined for lives of crime because you are afraid of perspective

No, no, a little murder is ok, as a treat.
(But only if you are from the valley GangViolencia, otherwise it's v just sparking assault.)

You are very lucky to have never been around an environment where you see and learn these things.
