FTP warrant Arrest, Search, Seizure, Warrant

I was arrested on a warrant for FTP. It just clicked to me they never sent me anythng in the mail letting me know I missed a court date or that there was a warant issued for FTP.Aren't they supposed to send you something in the mail?Could I possibly get the FTP charge dismissed simply based on that?

Thanks

 

Yeah but I thought they were supposed to send you something in the mail telling you about the warrant if you missed court.

I didn't even know I had a court date in the first place til this past weekend.I was arrested 2 years ago on disorderly intoxixcation.THey let me go ROR about 2 am while I was still drunk.I don't remember much about the nite which is why I'm assuming I was still drunk.I had everything I went out with the nite before but no paperwork telling me about a court date.So I figured I was lucky it was a bad nite but they let me go.Now l2 ast Sat they arrest me telling me there was a warrant for FTP for a court date 2 years ago I didn't even know about.It just doesn't make sense to me.Could any Lawyer look at the facts fairly and really think they have much of a case?
