Police say tensions have eased up since Sunday's deadly brawl between motorcycle gangs in Waco, Texas. But they warn that the gruesome shootout that left nine people dead and 18 injured was likely not the end of violence between biker gangs.

In fact, authorities were monitoring reports Tuesday that more motorcycle gang members could be headed for Waco.

The approximately 170 suspects arrested after the Twin Peaks bloodbath were all charged with engaging in organized crime, with bond set at $1 million.

Judge Andrew Napolitano said on "The Real Story" that the bond number is high if the people are in custody simply because they were members of the gangs.

"If they're in custody because they engaged in the violence, if they were shooters who didn't get shot at, then the bond is not high, and I think it will even itself out or it will be reduced," Judge Napolitano explained.

"We learned this morning that these gangs are not doctors and lawyers and dentists on motorcycles on weekends," Judge Napolitano said. "These are gangs that engage in crimes and use the crimes to enrich themselves and further their own existence. That is a classic criminal enterprise."

"This is going to get worse before it gets better. And the good news is that the feds and the folks in Texas are aware of it and on it."
