Were I you, I'd pen a quick note apologizing that you have a medical condition similar to Tourette's that you're attempting to treat, but that can get loud when you're under stress, and are sorry if you disturbed him.
If he's like most cops I know... An explained source = mostly free pass
Cops are trained to run towards trouble, but also usually disinclined to stick their nose into benign matters. Double that off hours. Just like doctors don't want to see your rash at the grocery store. So they tend to let a lot of stuff slide around home, because they know how often "Someone screaming for their life" is actually a heated argument with the darn garbage disposal, enviable sex, children being children, a mostly deaf spouse, mother in law come to visit, etc. With more than half of the possibilities equaling one or more parties wanting them to take sides. Given a reason not to? Most LEOs I know jump at the chance not to be involved. Unless there is actually something they can do / immediate threat to life... And not a clogged drain someone wants them to spend an hour taking apart and fixing. But they also tend to be pretty Hypervigilent surrounding unexplained noise. Shouting, banging, etc. tends to get under their skin even faster than it does PTSD. When they don't know the source. It eats them. Investigate? Ignore? Investigate? Ignore? Investi-Aaaaargh. Quiet! Just quiet! Is it too much to ask for quiet??? I'm off work! I don't want to have to go investigate unexplained screaming in my boxers. Again. If you make me come over there, I am not putting on pants! Why me? Why am I the one who always has to... Grumble grumble grumble.
