However, Greenknight121, crime rates both in the US and many Western countries has fallen dramatically since the 1980s - though there are many supposed reasons, might one of those be that ex-mil people are no longer "beaten down" then "built back up", in such a manner that they are no longer able to deal with any non-institutionalised life?
I doubt the current gang problem is any different from any other gang problem experienced by the mil in the last 100 years: the pertinent point is that they have neglected to tackle the problem as they are too busy bogged down in too many frontline battles...
