Impeach the president. End racism. Save the planet. Stop the war.
The extremists and protesters who spread their messages of love and hate across the Big Apple a half-century ago were secretly surveilled by the NYPD, a trove of newly unearthed photos reveals.
Cops had their eye on the deadly Black Liberation Army, and somehow got their hands on a useful shot of 13 beret-wearing members of the radical terror outfit posing together for a group portrait.

In 1971, five members fatally shot Officers Joseph Piagentini and Waverly Jones, who were partners, in Harlem. The next year, four joined in fatally shooting Officers…
