That's the truth. Doesn't look like this person has ever been exposed to any tactic or experience in that area.
Also, if I understood the diagrams of the church that have been posted, it appears the suspect broke several exterior windows, is that correct? If that is an attempt to disguise this as a burglary, that is also completely off base. Burglars typically have a single point of entry, and don't break windows unless necessary. It sure APPEARS the suspect wanted to try to make it look like a burglary, though, with the actions inside the church. Absent that angle, it would have been wiser to break in, crouch in a corner and wait.
