I knew a young couple, he was a Navy commander, nice subdivision in San Ysidro, about thirty years ago.
Just about every morning they found evidence, trash, of illegals camping in their back yard.
I can beat that - saw a guy stab another guy in the street in front of my apartment building. I just happened to be looking out the window at the ocean view at the time. (The ocean view made living there worth it...most days.)
I called 9-1-1 from the neighbor’s. We were very low-ranking Navy at the time and so absolutely BROKE that we couldn’t afford our own telephone.
