>> Boston's ramping up security preparations ahead of a planned rally by far-right activists on Saturday. The city trying to avoid at all costs a repeat of the deadly clashes that rocked Charlottesville, Virginia, last weekend.>> There'll be a zero tolerance for any violence tomorrow. We will not tolerate any misbehavior, any violence, or any vandalism whatsoever.
>> Boston bureau chief, Scott Malone.>> Boston police have a long history of controlling large street events like this one. And they've been preparing for this rally for more than a week now. They say that they'll have at least 500 officers on the streets, more if needed. And they put in place measures, including a ban on anything that could be used as a weapon.
So somebody carrying a sign, can't have the sign on a stick, Police Commissioner William Evans said.>> Speakers at the Boston event initially included libertarians, militia members and advocates for men's rights. Some of them attended a rally in Virginia a week ago, which included neo-Nazis and Ku Klux Klan members.
Violent clashes broke out when they were met by anti-racist demonstrators. One woman was killed when a suspected white supremacist rammed his car into a group of protesters. Far-right groups have planned more rallies since, some saying they are encouraged by President Donald Trump's saying that there were many, quote, fine people among the white nationalists, and his insistence that blame for the violence lay with both sides.
>> Hatred only sows more hatred, and that's we are against.>> Organizers of the event do bill it as a free speech rally and earlier this week condemned much of what happened in Charlottesville, both the violence as well as the white supremacist views that were aired there. They said that this event is not about white supremacy.
>> Anti-racist groups in Boston are planning a counter-demonstration.>> The counter-protest to Saturday's free speech rally is expected to dwarf it by at least an order of magnitude. Organizers saying they are expecting up to as many as 20,000 people. That may be high, but I think a turnout of several thousand people is quite reasonable to expect.
>> Right-wing rallies over the weekend are also planned for Dallas, and Laguna Beach, California.
