More liberal BS.  If some yahoo with a samurai sword wants to kill people, I'm okay with the police taking his sword away and locking him up.  There are LOTS of options to do so that don't involve the use of "deadly force".  If one of my relatives were later harmed by this "disturbed" person, I guarantee that someone would regret that stupid decision to stand down and let the guy disappear.  No wonder the Portland PD is such a mess.............
