With the exception of celebrities with legions of fanatics, just being a person of interest by the police can get a man killed by an angry assuming mob. Even after the dust has settled and you’re found not guilty getting your reputation back is difficult. The system that falsely accused you or names you as a person of interest will not help you to clear your name.
The reality is that association with persons involved in crime may lead to one being falsely accused. Protect yourself by staying on your path, maintaining your integrity and setting standards for friends and associates.
Life is like a game of chess, learn from the past, plan for the future, live in the moment.
