Yeah I found that quite surprising, too. It's not like I'm not consuming action-blood-guts-media, but that's generally more disconnected from reality (scifi, WW3, fantasy etc.). I can see how watching crime shows depicting this-could-really-happen-in-your-neighborhood crimes on a daily basis could shift perception. These often tend to heavily lean on stereotypes and tropes, too, so I wouldn't be surprised if these shows reinforce them.
