Personally, I believe we should abolish the death penalty. If they can ID anyone responsible for the death of the officer, those people should absolutely get the death penalty if we are to have it at all. It's not an effective deterrent for sick individuals like serial killers who are a threat to the general public without political or financial motivations. Doesn't seem to be a deterrent for people who end up about that life. It may be a deterrent for others to not get sucked into conspiracy theories and try to overthrow the government. But I think a long prison sentence would also do that.
