Margaret, it's pretty hard to argue against doing "something different" when "something" remains undefined.  Have you any suggestions?

I am heartened by the British resolve in both London and Manchester to carry on as normally as possible in the face of tragedy -- and sickened by Corbyn making political hay out of it.  He has spoken out against increased surveillance in the past, making him a hypocrite as well as an opportunist.

Terrorism is notoriously difficult to stop.  The cells are loosely organized, if at all, and there is usually little warning that a tragedy is in the works.  

Heightened vigilance is, of course, required.  So is prosecution to the full extent of the law for those found plotting attacks.  I don't think even civil libertarians would object to a closer than usual eye on any group known to be hostile to the status quo.

But we must never give in to the temptation to become a police state, intern people based on faith, or act outside of the law.
