Landlord telling people to enter the residence while I'm at work UPDATED

My landlord has a storage closet in the house and he told his friend to come in today while I was at work. The front door has a deadbolt so rather than using the side door he jumped in through my bedroom window and went and got whatever from the storage and left.

My landlord texted me to tell me he was very disappointed that this is the second time in a row that I was not allowing access for his random friends and family to come over and check on the place (last time I actually was at the doctor's office when apparently his mom couldn't get in without more than 1 hours notice).

He's sending over his mother in the morning which he messaged me at 9pm. I really want to just leave the deadbolt unlocked and just call the cops and tell them she's trespassing when she shows up.

Also the icing on the cake of all of this is apparently the thing that his friend was coming to get was a gun that he was storing with my landlord because he is a prohibited possessor, not allowed to have guns because he has domestic violence charges.

Update: The mom did end up coming over. She started saying she's in charge now and went back and forth about asking me to do maintenance on the outside of the property that I'm not responsible for and just talking bs I said that they can just evict me if they want and then started screaming up until I said "If there isn't anything else can you please go". That made her pretty irate and she said she was calling the cops.

She started tossing things around the kitchen and I went into my room locked it and called the cops. They showed up in about a minute and asked her to leave and she said that the whole reason that she had came there was for a piece of furniture or something. They took her over to a couch that was probably bigger than her car and she tried dragging it for about 3 feet then said she doesn't need it and left.

The landlord ended up messaging me afterwards telling me I was never a tenant here and he's going to get proof and then asked if I could be out in a few weeks.
