Retired Federal Law Enforcement, Military, Hostage Negotiation Team Leader here…
Ask yourself, Why, with all the available Non-Lethal Weapons (The ones you do and don5 know about), did they kill the Texas Synagogue Hostage Taker? Especially, if he didn't kill/maim ANYONE?
Now I'll put my Intel Analyst, Counterintelligence, and HUMINT Interro(Gator) hat on…
If this was a Terrorist related incident, then why kill this valid source of intelligence? Who is responsible for In-Country (United States) Terrorism Investigations AND Hostage Negotiations???
ANSWER: THE FBI.
Now my Statistician Hat…
What are the chances (probability) that this occurred on the same day of the year and same [time-frame] as the Donald J Trump Rally?
ANSWER: MATHEMATICALLY IMPOSSIBLE! (99.995% PROBABILITY THIS WAS A FALSE FLAG)
