Ah, good question that could have a slew of potential answers. The bad: they're incompetent at judging people or with whatever power, spell, etc. they're using.

The good: They see something we as individuals might not yet envision or they're dealing in potential.

[ That Kisuke has no access to his powers lends no solid clue. Perhaps whatever is happening cannot support the abilities of a Soul Reaper, or some other factor that he's yet to discover (though he has plans to do so). However, if the neutralizing of his abilities is intentional that raises far more and less desirable questions. ]

Did you get a weapon?
