How can the third most important person in our government have such bad security?
Lots of security can make you a target.
A person with a security detail is either very rich or a prime target.

Security shift changes can arouse suspicion.
Most drug addicts will want to lay in their nightly supply before midnight, so crime at 2:30am is far less.
Yep.
