So far, CNN and other legacy media are referring to the perp as simply "a shooter."
This means we can rule out a 30-50 white male with a scraggly moustache, dressed in jeans and a dirty NRA t-shirt; since they would certainly have said so on the slightest hint.
Same for a chubby Asian youth in a black D&D t-shirt.
If the shooter were simply "a man" he might be Black or Hispanic.
A woman in a burqa is still a possibility, as is the offically non-existent perp-category of "M**dle-E***tern male."
If the PC/dhimmi authoritites stall on releasing a name or any reference to ethnicity, we'll be sure.
WOW ! You have the media PC nonsense almost down to a science!
