These photos show how chaotic Boston got after Sunday’s protests over George Floyd - The Boston Globe

Thousands of protesters took to the streets of Boston on Sunday to protest against the death of George Floyd, a Black man who died after a white Minneapolis police officer pressed a knee into his neck for several minutes.

However, the protest — which was peaceful for most of the day — turned ugly once the sun set on Sunday, as some demonstrators clashed with police, and others looted storefronts throughout the city.

Here are photos from Sunday’s demonstrations and their aftermath on Monday.
