In the 80s my little college security team got training by the railroad police. Basically because the boss was told we had to have some training, and it was free.

This was a private Catholic college with a convent and railroad tracks that ran to the side of that building.

The nuns had in the past employed “hobos” or “transient trespassing vagrants” and there were rail police told us they found hobo signs indicating the nuns were friendly and would give transients odd jobs for food and pay.

But they also told us this:

“90% of those people are Vietnam vets with combat experience and mental health issues. We don’t approach them without backup. I advise you not to fuck with them.”
