Are libraries everywhere in the US seeing an increase in disturbances?

I returned from personal leave in September and since then we have had to call the police at least 10 times. These incidents have involved verbal assault, threats, being cursed at, patrons charging staff like theyre going to hit us, people non-responsive, vandalism, and sexual harassment. Majority of these incidents are from homeless patrons. It's getting harder and harder to deal with this. I'm getting to the point where I'm very nervous around anyone new who comes in and looks like they might be homeless which I hate because I know that is prejudice but it is truly a trauma response. We have plenty of folks who are struggling with housing who come every day and they are very nice and we enjoy them but lately some of our regulars who have mental illness have started to escalate and we are seeing a lot of new faces who are causing problems. I have dealt with a lot of things working in libraries for almost 20 years and for the first time I'm actually starting to feel scared at my job. All of my experience and a MLIS have not equipped me for regularly dealing with violence at work.

Am I alone or is this happening with others too?
