train travel while armed?

Hmmm...I wonder, does this apply to FLEO’s as well? Most of us can get onto airplanes armed...

I wonder if this cuts both ways. If you traveled armed and were forced to defend yourself against a terrorist; could you sue Amtrak for deliberate indifference; failure to provide adequate armed security on the train for a foreseeable event? I’m not a lawyer but it seems that many of the frivolous lawsuits directed at police departments would apply.
