When you know that someone can come to your house to drug test you at any time, yes, it is unreasonable to grab a gun and point it at a stranger. That's reckless endangerment. I have many friends who own guns and I'm currently looking to buy one for myself, though more for target shooting than home defense. I'm 100% in favor of gun ownership. The thing is, when people take reckless actions or commit an atrocity with a firearm, you get a lot of people looking to restrict gun ownership. Guns aren't the problem, people who are mentally and/or emotionally unstable are the problem. Not trying to turn this into a debate on guns, but my point is, taking actions like this are dangerous to other people and also lead to new, more restrictive gun laws. People who pull their gun out just because someone parks in front of their house probably shouldn't have guns.
