I suspect many government representatives (especially left leaning)are reconsidering unsecured discussions with citizens in the community, and revamping their security provisions.
Hopefully, this does not signal an end to local community discussions of this type...but, maybe they will become a rarer thing someday?

It only takes one nut, with an axe to grind. Nuts can easily be encouraged or provokes. I suspect they can always find a victim, no matter what the age.
