I find it interesting how often people try to justify police shootings by pointing out all the bad things the deceased was doing. Perhaps some reminders for those who aren't clear on the requirements of the Fourth Amendment:
1. Cops are not allowed to kill you for being drunk.
2. Cops are not allowed to kill you for resisting arrest.
3. Cops are not allowed to kill you for stealing, even if you steal from the cops.
4. Cops are not allowed to kill you for trying to escape.
Cops are allowed to kill you if and only if a reasonable officer in that situation would think you pose a threat of death or serious bodily injury to the officer or others, or in the case of someone trying to escape, if and only if a reasonable officer in that situation would think that the escape would pose a threat of death or serious bodily injury to the public.
In this case, it might be possible that the officers in question have a defense on this point, if the taser the deceased stole can be considered a deadly weapon. According to Georgia lawyers who have opined on the subject, a taser is only sometimes considered a deadly weapon, depending on the circumstances of its use.
but a taser certainly poses a risk of serious bodily injury, which you stated is clear justification for a police killing
