Don't taser me, bro.
I originally supported sub-lethal weapons like tasers because it appeared that if force had to be used, pain was preferable to injury or death. But I get the impression now that the supposed "harmlessness" of these devices is only an excuse to use force more frequently than it would otherwise be used.
Sub-lethal is not the same as non-lethal. Getting hit by a rubber bullet is preferable to being shot with a hard round, but it still can kill. People have died from tasers, too.
