Oh, they totally do. That’s why I’d suggest not punching a Nazi in front of the cops, even if they 100% deserved it. The cops will arrest you much quicker than they will a fascist even if you do the same exact thing.
And also definitely YMMV on whether this works at all, I’m in Massachusetts where the cops have to at least pretend they’re doing their jobs so they will typically detain Nazis if they take an actual swing at someone. Other states this might not work at all.
Not OP, but we have a bidet and a basket of cut up t-shirt cloths next to the toilet that are single-use and then go in the wash every week. I wouldn’t personally reuse washcloths for wiping out of fear of UTIs, but I’m extra paranoid.
