olent demonstrations met with water cannons. The message the most hardcore of protestors in Hamburg have for US president, Donald Trump, and other world leaders here is clear. Welcome to hell. I'm Reuters Matt Larotonda at this G20 Summit. That welcome sign I just showed you is from an old theater called the Road to Flora.
It's now a commune for anti capitalists here in this city, and the members are gonna be among 100,000 protestors beyond the layers of security at the conference hall behind me. Now, the vast majority of those, completely peaceful, but authorities think that about 8,000, or 1 in 12 have the potential to enter clashes that could go well into the weekend.
There's 20,000 police called up for this event. And if they can't keep control, it's gonna be a huge loss of face for Chancellor Angela Merkel. That's because she could have chosen to hold this summit anywhere. A secluded resort, for example, where many similar events have taken place. But instead she chose here, the city of her birth to send her own message to leaders like Trump, like Turkey's president Erdogan, like Vladimir Putin, and others she's butted head with.
Freedom of speech and the right to protest is just fine in a confident democracy. A message that could get lost if the demonstrations see real violence. This sign hung right across the street from the exclusive hotel where she met Trump face to face. They said nothing to press during the brief moments cameras were allowed in, smiling.
But make no mistake, on Trump's disregard for the Paris Climate Accord, on free trade, immigration, this won't be the easiest of summits.
