It looks like a pretty clear open and shut case. But there's a few things that concern me.

1. There was a fire drill earlier in the day. What are the odds that on the day of a fire drill, a shooter pulls the fire drill, confusing everyone? All false flags in the past start off as drills, which confuse everyone involved.

2. Cruz says he was hearing voices telling him how to carry out the attack. He himself did not refer to these voices as demonic, but law enforcement did.

3. It's very possible the goverment WAS aware of this guy, and pushed him over the edge with a technique called "Remote Neural Monitoring". Remote neural monitoring is a real program, where images can be sent directly to the brain, bypassing the eyes, and sounds can be sent directly to the brain, bypassing the ears via satellite waves.

4. I live in South Florida, and was a victim of Remote Neural Monitoring, and I am lucky I am still be here today. The technique will make you think it's a religious experience, feels like you are stuck between dimensions or something.
