You have some links proving it was a strobe light running as the shooting was happening? Not calling you a liar, just wondering where/what your sources are.
I’ve posted and posted and posted, on thread after thread, links to video and the police scanner recording. I’m freakin’ tired of it. Do your own research.
One tip, the answer ISN’T in videos titled “PROOF OF A SECOND SHOOTER” or on 4chan or coming from Alex Jones.
