Limits on no-knock warrants being cancelled by magats

Breonna Taylor was shot dead by a thugs who had burst into her home without warning, and then fired wildly. Americans demanded and got policies to limit no-knock warrants. But now magats are canceling the limits. Why do this? I don't think it will make any legitimate activities of cops significantly more effective. I speculate that magats expect that killing people that they can demonize (for instance, blacks) will win them increased support from their base.
