Usually Presidents (or other persons) get assassinated by people who hide their guns, not those who carry them out in the open.
Just something to think about.
Thank you for contributing an irrelevancy.
The crazies with the guns are not very likely to manage to assassinate, but they are very likely to kill
someone purely on impulse. The whole danger of having ordinary fools walking around with guns is that ordinary fools get angry. Ordinary fools, particularly the right-wing american variety, are very excitable and only marginally in touch with reality.
Yes, we may feel some comfort in knowing that their incompetence means important people will probably escape their murderous wrath, but does that mean we need have no concern whatever for public safety?
