Rare in comparison to what, the total number of searches across the platform?
But even that is the wrong focus. One could make the same case for rejecting police body cams because incidents of police abuse are rare, relatively speaking.
The real issue is that the platform isn't completely locked down by default with strict access control grants, monitoring, auditing, etc. Shoot I have way less access at my work to data and systems which do not have that level of sensitivity and have to go through multiple approval steps to be granted anything new.
But I guess those things don't help the sales pitches. To be fair policing the police isn't flock's job and doesn't make them money. Laws and regulations are the only real vehicles of change.
