In the US, 1st Amendment includes not only free speech, but also freedom of assembly.

A civil rights attorney working for Harvard Law School posted the contrasting two-scene video below, showing apparently different attitudes towards public gatherings with political elements.

In the left panel, Columbus Ohio police disperses a crowd of college protestors, apparently gathering to support Palestinian rights. In the right panel, the same police force stands by peacefully, as a gathering of white supremacists flies the swastika flag, signaling tolerance in the name of 1st amendment rights.

Is the apparent change in attitude a result of deliberate shifts to policy, in the interpretation of the 1st amendment?
