I don’t think they were testing security at government offices. I think they were hoping to plant a bug and/or a wiretap in Landrieu’s office. They seem to think she’s got something dirty going on, and they’re probably right.
I just would use that as my backup..excuse. ;)
Yes, they had to be looking for something to take this high level of risk to enter a federal building housing Landrieu..the question would be, who would stand to be most embarrassed?
