Senator Schumer is calling for a TSA style no-ride list – for trains. This is unutterably stupid, because of the difference between planes and trains.
As John Lott points out, to protect trains, you have to protect all those thousands and thousands of miles of tracks. You don’t have to be ON a train to take it out.
So a no-ride list is absolutely pointless – and would be very expensive. Your tax dollars would pay for every single security agent, scanning machine, etc. required to implement any such ID requirement.
