Not arbitrarily: the freezing was targeted against political protestors.

They were going pretty damn far beyond "protesting" they were trespassing/loitering/squatting.

Loitering, dear god!

When done in giant trucks blocking traffic and making tons of noise and exhaust fumes for weeks it is a crime.

That sounds straight out of Russia or China.

Your article seems to support the idea that bank accounts were arbitrarily frozen.
