<human>: Can you summarize the given text in a few sentences?

First, excuse my english, I'm not a native speaker.  
I noticed in movies or TV shows that people always have good alibis whenever a crime is commited. The suspects were always in a restaurant where they had a fight with the waiter, in a plane, or in a fundraiser ball with half the town as witnesses. I'm often alone in front of my computer, the perfect guilty one.  
So, I want to know if redditors have great alibis for a random day. 
You can also give the chances you have the cop will believe you and cross your name from the suspects list.
<bot>: Imagine a cop comes by your door and asks you *"Where were you tuesday the 27th between 10PM and 1AM ?"*. What's your answer ?
