Very unlikely. Fireworks use against the police more common that you think. You’re just not going to see that many videos of them as it doesn’t help the narrative. A buddy of mine is a cop who had the unfortunate duty of being one of the riot police in my city and it’s not easy to keep your cool while having rocks, fireworks, and almost a Molotov cocktail tossed at you.
Don't dish out what you can't take. I've never seen an example of riots breaking out in a city before police instigate violence with rubber bullets and tear gas.
Also, if he can't keep his cool under those conditions, he has an obligation to change jobs because if he can't handle it he's just putting other people in danger.
I've only seen videos of police using flash bangs against crowds, which seems to be quite common in the these protests for some reason - completely inappropriate, just like shooting gas canisters or less lethal rounds at heads, not at ground level as they are designed to be used.
Haven't seen or heard of any fireworks, which you can be sure the police would not tone down in reports (probably describing them as explosive projectiles).
It certainly isn't easy to keep your cool if things are been thrown at you, but that's the job. It's not an excuse to violently attack protesters who are not throwing things or use inappropriate methods.
