John--- actually I am a prosecutor--- doing child support enforcement now, but I have done general criminal work. Prior to my service as a prosecutor I was a Court Commissioner ( Magistrate equvalent). The National Guard, unless called up( by the Governor) and maybe Federalized ( as in the case of riots and some disasters) probably cannot, Constitutionally, be a part of any State based security efforts. In Maryland, MDOT, through the MTA has a police agency, and, since MARC as well as MTA are divisions of MDOT, that police agency could probably be used to do New Carrollton type screening at any MARC station not used in common with Amtrak. If not, it probably wouldn't be that difficult to get enabling legeslation through the General Assembly.
The other option would be to create a division of the Maryland State Police to handle state railroad security. ( until the Feds took over security at BWI Airport, security there was provided by the MSP aviation division and those policing aspects which have not been Federalized are still performed there by MSP)
Generally, the biggest problem that we're going to have, regardless of what police agencies are given authority over what parts of the rail system, is the naturally spread out nature of railroads. It is impossible to provide police survellance of every inch of right of way, or on every railroad car which carries passengers no matter how sophisticated detection and screening equipment becomes. I think that railfans can help by simply being observant, knowing where to report suspicious observations, being understanding when confonted by an authorised security person as they do those things which are legitimately a part of railfanning, and being reasonable and prudent in how they conduct these activities.
One of the things that terrorists intend to do, and at which they are very successful, simply because of the threat of terrorist activity, is to restrict the freedom of movement and of activity of all of us. And I can see no way around having to live with these restrictions in the present climate.
