Interesting article. I hate when someone comments only to quote a paragraph of the article, but I'll make an exception because reading only the title may be polemic:<p>> <i>Researchers say this may be down to wearable cameras modifying behaviour through an ‘observer effect’: the awareness that encounters are recorded improves both suspect demeanour and police procedural compliance. Essentially, the “digital witness” of the camera encourages cooler heads to prevail.</i>
