MTA says patrols may increase
The Maryland Transit Administration issued a carefully worded statement indicating that it has ratcheted up security after the announcement of the death of Osama bib Laden.
The MTA statement said the agency's approach to security "remains comprehensive and multi-layered." He said passengers may see "some visible signs of changes and others not as visible."
"For example, there might be more uniformed patrols and more undercover patrols," the MTA state.
The agency encouraged members of the public to report anything unusual. It said the number to call with security information is 1-800-492-TIPS ( 1-800-492-8477).
