Was the Charlie Kirk Assassination a Professional hit?

This video asks the question was the Charlie Kirk assassination a profession hit? Near the end of the video he mentions the old man they first arrested claiming he was the shooter and the problematic nature of that announcement. 

If the FBI announce they have the shooter then law enforcement isn't going to set up a perimeter and would there by let the real shooter get away. That in itself is suspicious. This next video asks is the FBI lying about the Charlie Kirk shooting? 

The most obvious question is how did he get the rifle from the scene and stash it in the woods? One video suggests Tyler's job was to be seen on the roof. He was a patsy. Someone else took the rifle from the scene and someone else made the shot.
