The Fourth of July weekend is upon us and some people may be thinking about messing around with illegal fireworks in their backyards.

Fairhaven Fire Department spokesman Wayne Oliveira says that's a bad idea.

He says not only are they illegal in the Massachusetts, but they can cause some serious harm.

"They should absolutely be left to the professionals. They're very dangerous and unpredicatble and can lead to serious injury and/or death," said Oliveira.

Police will be on the lookout all weekend long and will confiscate any reported contraband. Possesion of fireworks can also result in fines and even jail time.

Oliveira suggests going down to the harbor or other organized show to enjoy the festivities.
