"It's always too soon to talk about gun control"

[Black Aeronaut]

I think what was really legendary about that massacre was that it was done by men under Al Capone masquerading as police officers. These victims, even though technically criminals, had no idea what was coming as the police had a certain rules of engagement they abided by in those times.

If you had a sudden mass-execution of people working in meth lab by a rival gang all posing as police, then that would certainly be memorable, and cause for grave alarm. (Bad enough that police act like gangsters sometimes, but to have them be ACTUAL gangsters disguise? Yeah.)
