Well when you end up committing crimes while being a US LPR you tend to get yourself in trouble and deported.

> “Whatever charges got a combat veteran deported are irrelevant,” he said. “No one deserves to be deported after sacrificing, doing the things these young men and I had to do. These young men died over there. They were destroyed over there. They were other things when they came home.”

I really wouldn't want someone who has a violent criminal history to get citizenship to be honest. If it is non-violent crime that does not involve crimes involving moral turpitude I don't have an issue giving them another chance.

Also not everyone who served did it honorably or is a good person. I worked with plenty of bad people while I served and deployed with them knowing they were not good people.
