Yes and we, as the people, should keep an eye out and keep a check on the government, authority. We should examine these situations and determine what crosses the line and what doesn't. But under no circumstances should anything be absolute yes or no. What you are suggesting is that those police were not smart enough? How do you know? What I'm saying is you can't really be certain that what they were doing was wrong unless you understand their position completely. You're making your decision, which is predicated on the fact that things are absolute right or wrong, based on limited information from an article.
I'm assuming all you did was read the article. Well if the world was really black and white, you could easily determine the righteousness of their actions, but the world isn't black and white. You can't assume their actions were unjustified simply because it leans a little towards that side. Just as sacrificing our right to yell fire in a crowded theater, while it means a restriction on our liberty, doesn't mean it's absolutely wrong. And like I said, i agree some of their use cases actually do seem like harassment.
If we let cops become bullies whose own discretion is OK when it comes to harassment, etc., we are throwing away quite a few rights.
