Can I get in trouble for making a "bullshit" twitter account?

[Matt]

about 4 days ago I thought it would be funny to make a twitter page and basically I would tweet about all the crazy and just random stuff that happens. I posted a few tweets about people (most of them didnt have names in them, but like 2 did have names) and I also tweeted a video that I didnt upload, about a fight. the video was taken down, and I didnt really care. I then posted a tweet about a teacher and saying that hes a dick, and he doesent give a crap about students and lies his way out of situations. today in school, everyone some how nows its me, but I keep denying it, because I dont want to get in trouble. But everyone is telling me that the police are investigating, and all this shit. I was wandering if I can get in trouble, for what I tweeted and stuff....
I dont think I could, I have my rights, and I have a freedom of speech and press, but Im just scared they will come and take all of my computers and check them..

thanks
