I guess it's "lawful" if it becomes "law." Nice thing is it wouldn't be subjective, ever. No way. If they found:
"Screw the fuzz" - "Kill the pigs" - that's OK; hippies are Dems, need them.
BLM police death threats and "Kill white people" - that's OK; can't be racist.
"Kill SUV drivers" - "Kill Trump fans" - that's OK; more Dems and Green friends.
"Death to America" - "Kill all infidels" - that's OK, welcome all beliefs.
Violent criminal Latino gangs and individuals - that's OK, give them a chance.
Foreign agents - illegal immigrants - that's OK, no proven threat.
NRA and gun org/forum members - slow down, need more scrutiny!
Black and Latino Republicans or Trump fans - whoa, major red flag!
Legal immigrants - suspicious, back of the line please!
Constitutionalists - we need a SWAT team at this address pronto!!!
