So far, this is one incident on a train. There must be thousands and thousands of train routes run each day, with tens of thousands of journeys taken on them. I don't think we're at the point where we need to put arm guards on every train or, as someone suggested on the news this morning, airport-style security to get on them.

We cannot completely control every public space. If these incidents become more common, then we might need to react, but let's not throw out more freedoms in reaction to the, understandable, fear that one attack generates.
