It matters that the actions of the police and other security agencies is appropriate to the threat.
In a war situation there are likely to be many, many lives at stake, and so it's logical that they should have a freer hand to do what they need to to save those lives.
But, we're talking about activists here, none of whom as far as we know are accused of endangering lives.
I'm not sure operations like this is about security of the state as much as fear of alternative cultures. The police have a long history of being very heavy handed with people living alternative lives.
This is still remembered by many for example:
The video shows the police being excessively heavy handed, they beat women and children and trashed the buses that were their homes, rendering them homeless. There was a TV camera crew there who recorded the whole thing for the evening news, the reporter was visibly shocked. It was never transmitted.
I'm not anti-police, btw, far from it! My SIL is a Policewoman and I have so much respect for her, she is one of the most moral people I know (and great company).
But I want to live in a society where people's basic freedoms and humanity are respected. And if they're not, then that matters.
