All good points posted already, but, I'll add mine:
At the end, you have a homocidal/suicidal maniac cult member come to you to talk. What do you do as an FBI agent? You pat them down, say, "Ok clean. Then turn your back on them and say "Let's go talk, follow us."
By all means DO NOT HANDCUFF THE SUSPECT.
Idiots. I never laughed so spontaneously and hard at a supposed 'drama' then that point last night.
And as mentioned before by etm, the 'backup' posse is 2 states away....again. Its such a regular thing, it almost doesn't register anymore. BUT...it was THEIR plan...they were following the car the whole time. What...in....the frick?
