Of course. The agenda is that everyone in Hollywood is a fool and that guns aren't dangerous. Only irresponsible foolish people are.
But the people that make movies are just doing their jobs the same as anyone else, and guns are inherently dangerous. They are made to kill people quickly and efficiently. And they do, even in a situation where serious precautions are being taken. No human is beyond making a mistake, and because guns are designed to kill quickly and efficiently, that's what they'll do, even when we're trying to be careful.
