I should stop watching The Following right before bed

I was in Detroit and was supposed to see this woman about a gang-related sting operation, but her brother found me and threatened to hurt me if I hurt his sister. He threw his forearm across my neck and pushed me against the brick wall of the building we were standing next to, and I assured him I wasn't going to hurt her so he let me go. Terrified, I immediately walked to the nearby police station and walked upstairs to find some officers to report this guy to. I found two female cops who had a puppy w/them in their office because they were going to be training it to be a police dog, but I wasn't sure I wanted to report this to the police for some reason so I turned around and started to go back down the staircase, but the brother was there. I didn't realized he'd followed me so I was really surprised. He asked, "Having second thoughts?" and grinned a creepy grin at me which immediately convinced me that I needed to report him, even if it compromised what I was supposed to talk to his sister about in the first place. So, I went up to the cops with the puppy and told them that there was a guy who was "casing me." They started to ask all sorts of questions about him, but he walked into the hallway and gunned down two cops outside of the office we were in and the cops with me radioed to other cops in the station to get their asses up there. Just as he walked past the office doorway that we were in and was about to turn the gun on us, more cops appeared in the hallway and shot him in the back of the head. All of a sudden, I was walking in the parking lot to my car and was on the phone with my mother, explaining to her what happened - without much detail, so she wouldn't get too worried about the work I was doing - and got into my car, which was parked at the end of the lot. Then, I had an overhead view of decimated areas of Detroit and wondered why anyone would want to live there.
