There is evidence from simulation studies that officers are too slow and reluctant to respond appropriately to women with guns and perhaps too fast to shoot at minorities.

You can disagree on political grounds but there are data for that. Training programs have been designed to correct for these biases and have been successful.

You may recall an old video about Surviving Edged Weapons - IIRC, officers got tagged by women as they underestimated the threat or didn't detect it.
