Well, IMO its like this....If you are a genuine criminal, meaning, you are constantly in and out of jail or prison, you are always in trouble with Johnny Law, you have no business in any professional sport.
However, if you got in a bit of trouble, took your spanks from the judge and cleaned up your attitude so be it. Chalk it up to "growing pains".
There is a huge difference between a "criminal" and somone who got in trouble. After all we are all human and can make poor decisions from time to time.
As a corrections officer my rule of thumb is you have no right to take anything from anyone else or inflict bodily harm to another in anyway. Outside of a ring or cage anyway
