A fact to remember...the police thought possible the guy was wired with explosives....another reason they withheld firing live bullits.
Under the circumstances they handled this well IMO...remember they also used a robot to remove the cover on the boat.
These guys were throwing handheld bombs at the police in the chase...he could have certainly had onw in that boat as well.
I never questioned how they handles this, I just found it interesting they were ready to assault and then the FBI HRT took over, I found the comment by the BPD guy saying TOO LATE when he was informed they would handle, they seemed pissed and had to be told twice to let them handle.
