None of which I am aware.
You probably already realize this next, but I'll toss it in just in case.
Someof the negative OC encounters reported happened in areas where the cops were thought to know better. Even here in Fairfax County, where the police have supposedly been pacified in a manner of speaking.
So, we still haven't quite reached the point where one can assume it is safe from police to OC. There is always still that chance you can run into one of that small percentage of cops who personally disagree and are willing to push things just for some harassment value.
