Again, if your argument is that tasers are not appropriate as a law enforcement weapon, then that is an argument for the manufacturers or the police hierarchy and civilian oversight with the power and responsibility to authorize the use of the weapon by the officers. It doesn't give you or anyone else the right to slander these officers as murderers. If it is an authorized weapon, and the situation calls for its use, then the cops absolutely should use it. Without question.
By the way, your approach is not conservative, it is narcissistic.
No, presuming that these men are innocent unless proved guilty is the conservative approach. If anything is narcissistic, it's your b.s. of implying these cops are "murderers" when they were, as far as we know, just doing their jobs appropriately.
