Not weird for potentially two reasons:

1. They didn't know about it. It's only recently that there have been popular youtube videos on the topic. Critical mass can take time.

2. Before "the whole ice thing" there wasn't a team of masked brownshirts terrorising communities and using all available technology they could access in order to undertake said terrorising. That these cameras are part of that available technology, the timing ain't weird at all. In fact, it was pretty predictable.

But, yes, should have been up in arms beforehand, but likely the knowledge and visceral demonstration of the effects were not known. Visceral demonstration does pretty heavy lifting.
