It would be nice if they weren't so twitchy. In this case, even if the officer should be charged in a perfect world, I can get behind not doing so. Making certain the guy who set up the swatting gets nailed properly is going to involve making arguments which a defense lawyer for this cop will be able to use to secure an acquittal. And working hard to nail this guy despite that just might hand the swatting jackass' lawyer enough to get off too. This is a set of cases where the DA has to decide which person they want to convict more and I can agree with choosing to go after the swatter and letting the officer off due to lacking confidence in the ability to secure a conviction.
