Forcefully grabbing someone's property to break it is assault.

TLDR: The law and it's philosophical/moral foundation and practical application doesn't run on what you think, and society is better for it.

Once again, the law says you aren't protected from being recorded in a public space, attractive or not. There's a plethora of ways to legally record people overtly and covertly in public. The law also says you can't grab other people's stuff and destroy it to prevent being recorded.

If the guy was assaulting her or disturbing the peace, she'd be justified in using violence to defend herself. She also had the option to talk to a cop and accuse this guy of harassment, which he was doing and others may have recorded evidence of that. But one is not morally or legally justified in starting fights, only finishing them as self-defense. The amount of force legally acceptable falls under the umbrella of the concept of "reasonable application of force" within what's commonly known as a "force escalation continuum".

So, no "creeps" shouldn't be allowed to record women as that would constitute harassment, but it's better to go through proper legal channels than pretend to be a tough-guy/girl and start an altercation that may have permanent consequences.

Her "ass-kicking" would only be acceptable to the point where she could be detained and arrested.

The guy with smart glasses could also be arrested and charged with disturbing the peace depending on what his exact actions were and if there's recordings of him.
