You ever see how much damage a 16-year old (even one 5'2") can do when cornered and out of control?

Like others here have noted:

- He ran from a routine (and valid) traffic stop

- At that point, Cops MUST regard him as wanted, has something to get rid of, and/or is potentially dangerous/armed

- They have a fraction of a second to decide.

- He refuse orders to halt even while being chased.

- He acts aggressively/uncooperatively once cornered -- and may still draw/use a concealed weapon.
