I'm a few days late in pointing to this on the blog, but earlier this week, the AP ran a story about new security measures planned for Amtrak, including random screening of selected passengers' bags. The short version: brown people on trains should probably brace themselves for [more] impromptu frisking:
Amtrak passengers will have to submit to random screening of carry-on bags
in a major new security push that will include officers with automatic
weapons and bomb-sniffing dogs patrolling platforms and trains, the railroad
planned to announce Tuesday.
The initiative is a significant shift for Amtrak. Unlike the airlines, it
has had relatively little visible increase in security since the 2001
terrorist attacks, a distinction that has enabled it to attract passengers
eager to avoid airport hassles.
