Yeah, the cops do jack shit about the fireworks, even though they are illegal. I actually wrote an e-mail to the mayor last year complaining about it and she basically said there's nothing they can do, too many complaints and they get to them when they can, but not a high priority thing.
Even though there were several brush fires started over the weekend from fireworks and in the southwestern side of the city, a house burned down because someone was using illegal fireworks.
