The "Internet of Things" keeps me awake at night. I may not have the skills, but I have read a ton of fiction and non-fiction, and I have a curious mind. Want to raid a house for warrants/drugs/national security? Packet sniff the building and build a pattern of comings and goings. If they have a baby monitor, break into the most likely UNENCRYPTED feed and listen inside the house from the station or anywhere in the world if needed. Monitor the fridge to see when they are likely to go to the store and pick them up outside the house/building. Monitor the wifi and keep tabs on the meta data of where they go online, what devices connect to the inside wifi building a database of phones, laptops and mobile devices. Do they have an Amazon Echo? That thing records voices in order to be able to issue voice commands.

This is even before we get into the XBox blatantly spying on occupants of the room it sits in, or smart TV's reporting your viewing history back to the manufacturer live and unencrypted.

You think the NSA is intrusive now? Wait until the local PD gets tech savvy and starts to do some of this crazy stuff; the judges are old and don't understand the tech and the prosecutors all see this as ways to increase confessions. "OK, we got the evidence to convict you, but we'd rather get a confession out of you. Here is a list of all the food you ordered through your refrigerator and your web browsing history."
