&quot;Mayors, police chiefs and state attorneys general said the lack of data is contributing to a dangerous trend in which police officers spurn aggressive tactics for fear of becoming the next officer to be caught on camera in a compromising situation.&quot;<p>First of all, mayors, police chiefs, and state attorneys general are the ones who should be collecting this data and the ones intentionally not doing so, so they should have no say in this. We gave them a few decades (or hundred years, if you wish) to become transparent and they haven&#x27;t.<p>Second, I fail to see how spurning aggressive tactics is ever a negative. Police officers should spurn aggressive tactics whenever possible. If they&#x27;re doing it out of fear of being caught on camera, they&#x27;re doing it because they know that their aggressive tactics are wrong. So good riddance, if this is actually true (doubtful).
