So what if I went into Walmart just screaming obscenities at the top of my lungs? At what point does my freedom of speech become disorderly conduct?
The US believes everyone has a fundamental right to peace and tranquility. When that is breached by someone screaming obscenities in a Walmart, he/she can be cited for disorderly conduct because there was a "breach of peace".
You can ask the question: Well, if someone is insulting you, isn't that a "breach of peace"? I think that is a fair question honestly, but our laws have double-standards sometimes. Take for example, a person murders a pregnant woman can/is charged would double homicide... yet, we allow abortion.
I personally don't like "disorderly conduct" because it's so extremely vague.
If there was a person screaming obscenities, the business should have the authority to tell the guy to shut up or leave. If he doesn't, then cite the person with "disorderly conduct" and/or trespassing. We don't get ALL our freedoms on private property (Walmart is a private business). I mean, even in this very forum, we don't get the luxury of free speech because there are rules we need to abide by. It's the terms we agree to by using their service.
