There are choices to be made. Take away a freedom for all, or severe and swift punishment for the perpetrators of certain types of crime.
I say we punish the guilty, rather than take away fundamental freedoms from law abiding people.
That is far too late to prevent the killing.
Severe & swift punishment is warmed over SSDD bullshit that does nothing to save a life.
Evil will always find a way.
Swift and harsh punishment does have a real deterrent effect though, aside from the punishment and sense of justice to survivors.
Our country has become too soft in this regard.
