I was in Aurora yesterday, lots of snow, and I know people who live there. And this is a real issue.
Denver is sort of a Sanctuary City. Not official but.
I remember when I came over, I was told to make sure small children wore their seatbelts, duh, anyway I mentioned that there seemed to be large families with children hanging out, in the back of the truck etc, told Police do not waste their time with them but would with me.
Also Denver downgrades charges to Agricultural Trespass, seems that does not attract the attention of ICE, what the true numbers are, well none knows.
Sadly lots of misinformation out there.
