That's reassuring.
That was almost 54 years ago. I don't believe any president has ridden in an open convertible since. The Secret Service has tightened things up considerably since JFK, Gerald Ford, and Ronald Reagan. They're certainly aware of how unhinged the lunatic left has become.
The JFK assassination though was a result of just pure idiocy and arrogance. Arrogance from assuming everyone loved him, and idiocy for allowing him to not only ride through the streets in an open convertible, but to incredibly publicize the exact route he would be taking the day before allowing any assassin to plan in advance. Its so insanely reckless that sometimes i wonder if there was in fact a conspiracy.
