What's your Scariest law enforcement encounter

So it was about 7-10 years ago on thanksgiving and my family was watching football and all of a sudden we heard a dog barking (I live in the country so dogs barking is pretty common) but our dogs were put away. So my dad and I went outside and we see a German Shepard and a long leash that he was attached to, and at the end of the leash was a SWAT officer. Behind them was a full SWAT team walking down the side of my property. All of a sudden we get a call from the police to stay inside and lock all of our doors and windows. Well about 2hrs later we got the all clear. Well come to find out there was a hostage situation 2 doors down and there was 10 sherif cars, 5 local cop cars and a SWAT van at the end of my road. It was a thanksgiving to remember to say the least.
