Is it my imagination or do people in Law enforcement have serious issues?

For years I have noticed that police officers (like my husband) seem to have serious emotional/mental issues. I was recently speaking to a psychotherapist and when I mentioned that my husband was a police officer he said that he had never known a cop (and he’s seen many) who wasn’t fucked up in the head and if a patient came to him with serious complaints about their spouse, 1 out of 5 times, they were married to a cop. What gives? Do they have to be crazy to get the job?!?!?
All of hubby’s friends are in law enforcement and I swear they all should have their guns taken away.
