Exactly my thought. Schools have doors, find a steel one, knock out the pins, and you have an improvised ballistic shield. What they lacked was brains. Or balls. Or both.
Easier to look at this as an op.
Look at where things were efficient:
1. 18 year old in a truck eluded BP agents
2. Conducted a running gun battle for 12 minutes completely exposed in an area ADJACENT to a school.
3. School, not locked down, is where the shooter holes up.
4. Single story, lots of windows.
5. Nine person SWAT team with no ballistic shield, no FLIR scopes, has no idea how to bead in on the shooter and take him down once he’s in the unlocked-down school.
6. Federal Marshals arrive on scene. Cops on scene have evacuated their own children safely at this point.
7. On scene LEOs effectively stop parents from evacuating their kids (completely unarmed women and men, by the way, and one woman figured out how to slip the LEOs and get it done - good job LEOs! Couldn’t stop an unarmed woman from getting in the school)
8. BP Agent who obviously had not been read-in gets in and kills the 18 year old transgender kid after 90 minutes, a car chase, a 12 minute running gun battle.
9. 18 minutes of 911 tape is missing.
That is an op. That is not incompetence.
