Jakarta is consistantly on the
State Department's Travel Warning List. Since the September 2004 bombing at the Australian Embassy (down the street from our office) and the August 2003 bombing at Marriott, security around the city has been tight - especially around spots where Westerns tend to congregate (like my hotel).
Before you enter the hotel. there are 4 security guards who use mirrors to check the bottom of the car for bombs. They will then open all of the car doors, trunk, and glove compartment to inspect. Once you enter the compound, everyone has to go through a metal detector. There are also guards armed with machine guns stationed around the perimeter of the hotel at all times.
I haven't been to the American Embassy compound yet, but I hear the security is pretty brutal there. You can't bring in any laptops/cell phones that are not US Government issued. They're afraid that someone will be able to detonate a bomb from the inside with a phone.
I'm not sure if all this security make me feel safer, or more of a target.
I think I almost feel safer in Aceh!
