Sure, there is great potential for abuse but I bet that the people being prosecuted will have multiple sets of evidence gathered against them because the police know this is controversial. From the Arizona Capital Times:
Arizona Senate votes to seize assets of those who plan, participate in protests that turn violent
Claiming people are being paid to riot, Republican state senators voted Wednesday to give police new power to arrest anyone who is involved in a peaceful demonstration that may turn bad — even before anything actually happened.
SB1142 expands the state’s racketeering laws, now aimed at organized crime, to also include rioting. And it redefines what constitutes rioting to include actions that result in damage to the property of others.
People's views pro and con:
Quezada said, though, that everything that constitutes rioting already is a crime, ranging from assault to criminal damage, and those responsible can be individually prosecuted. He said the purpose of this bill appears to be designed to chill the First Amendment rights of people to decide to demonstrate in the first place for fear something could wrong.
But Sen. John Kavanagh, R-Fountain Hills, said that chilling effect is aimed at a very specific group of protesters.
“You now have a situation where you have full-time, almost professional agent-provocateurs that attempt to create public disorder,’’ he said.
“A lot of them are ideologues, some of them are anarchists,’’ Kavanagh continued. “But this stuff is all planned.’’
There’s something else: By including rioting in racketeering laws, it actually permits police to arrest those who are planning events. And Kavanagh, a former police officer, said if there are organized groups, “I should certainly hope that our law enforcement people have some undercover people there.’’
“Wouldn’t you rather stop a riot before it starts?’’ Kavanagh asked colleagues during debate. “Do you really want to wait until people are injuring each other, throwing Molotov cocktails, picking up barricades and smashing them through businesses in downtown Phoenix?’’
Senator Kavanagh has it exactly correct. We have seen James O'Keefe's videos where he infiltrated and videoed the people planning the inaugural protests - the three ringleaders were subsequently arrested on this evidence. This is a wonderful law when applied carefully with sufficient evidence.
