That's what I was asking -- why do you believe this? What is your mechanism for safety in numbers? If it's "criminals fear being observed", that doesn't hold now that catch-and-release is standard practice. If it's "criminals fear being outnumbered", that doesn't hold when the crowd will be prosecuted if they attack. The only mechanism left for safety in numbers is hoping that criminals feel shy.

This seems intuitive to me because I would never risk fighting someone in the street over some crime, so I don't see why having me around would deter them at all. The same goes for maybe 90% of the people I know. We're weak and docile, even in numbers.
