"no threat to public safety"
with
agents were wearing protective equipment for their safety
and
Chamberlain could be armed and dangerous
and
Chamberlain owns a Nissan that reportedly could be rigged with explosives.
I think that the threat is exaggerated and misleading, because that's what both the FBI and the press do. (What does "could be rigged with explosives" mean exactly? Any car "could" be rigged with explosives.)
and how would the FBI know/worry about an explosive rigged car? They aren’t telling everything found at his apt.
