Yeah, I think it's a dangerous precedent to set for a county commissioner to openly call for public execution.
I think that should be on the table for the worst offenders, like trump and most of his cabinet, musk, thiel, etc.; But it's for the courts to decide whether their actions amount to treason and what the sentence should be. That power doesn't belong in the executive branch, not beyond appointed special counsel to investigate wrongdoing to bring it before a grand jury.
That being said, this commissioner literally said he wants to "make america great again" so clearly he drank the trump koolaid and is only upset about this because it's blowing up in his face enough for the constituents he cares about to raise a fuss.
That definitely is not a good reason to call for executions.
I'm not saying the Flock CEO hasn't committed what amounts to treason, but again, that's for the courts to decide. The US government let him do it all for this long, so it's not like he was subverting them or anything. This smells like making him a patsy to avoid accountability for allowing it to happen in the first place.
Also, it's not like killing off the CEO will fix the problem. They'll just replace him and continue on with business as usual. What needs to happen is Flock as a company needs to be dissolved, the shareholders held liable for damages, the cameras removed and destroyed, and their data centers and other properties, hardware, infrastructure, etc., all need to be liquidated, databases wiped, drives destroyed, etc. etc. etc.
Executing the CEO achieves none of that. All it does is normalize state-sponsored violence.
