What is the best way to rid this country of Gangs.1. jail 2. education 3.Deportation or4. eradication.?

Same reason for most everything, the consequences are not harsh enough. Too many people feel bad to send someone to hard time. Perfect example is prostitution. All they do is take em to jail and then release them.

All of the above, well you can not actually deport a citizen but those who are not and in gang activity should be gone.... yesterday.

This won't be popular, because it takes people of character, and it's "too hard", but...

Solid, emotionally stable families is the only way to create a solid, emotionally stable society.

There are a few genetic anomolies that create disturbed individuals, and that's never going to change.

Can't just keep sweeping the problems under the rug (i.e. jail, deportation, genocide)

Gang members should be used in colonization efforts in Iraq and other volatile nations when such wars against those nations turn unpopular..

No one will care if they do not succeed and if it works, great.
