Please don't misconstrue this a me defending this guy...but I'm curious.
What if he was once an MS-13 member but left the gang? Do the tatts forever doom a person? Or can you ever leave once you are a member?
We all know you can have a change of heart, Jesus provides such a transformation... but also if not forced to have the tattoo (and I am not sure if MS-13 forces the tats), I imagine one can only try to cut the tattoo off or ink over it if one wanted to distance oneself from it's implications.
I imagine most liberals would say yes, MS-13 can be rehabilitated.... but if asked the same from some smuck that has a Nazi sign on his face would say the opposite.
Most MS-13 members do age out of most of the violent aspects of the life, but they also tend to do other things for the gang in exchange (hold inventory, hide members). Thus they still act as functioning parts of the gang.
It is a complex question... and does a country need to do a thorough investigation which is subject to deceit or just take it on skin level... I lean the latter, just remove the risk, some here want to spend a ton of money and give more benefit of the doubt that I do. YMMV
