Just take a look at the quote here:

"Sandy Hook Elementary School shooter Adam Lanza armed himself with hundreds of bullets on Dec. 14 before he entered the Newtown school. But he also did one more thing.

He put in a pair of earplugs.

Investigators don't know whether the earplugs are significant to their probe, but they have speculated as to whether Lanza used them because it was a habit from shooting at gun ranges, or to muffle children's screams during his shooting rampage.

It is one more strange detail left behind by the strange, rail-thin 20-year-old"

Just set the earplug issue aside for a minute and look at the quote and THINK.

Armed with hundreds of bullets it says. They also told us the two pistols, and apparently a rifle? Or did they discard that one? I can't keep up. Anyway, add a vest, the clips.

Put it all on this "rail-thin 20-year old".

Let's have a mock trial. We'll use a volunteer of similar proportions to those attributed to Lanza's. Then we'll outfit him with all the aforementioned accoutrements.

Then I'd instruct him to climb through a simulated shot- out door.

And watch him topple over like humpty dumpty after taking two steps.
