Generally, but not necessary always the case (and I have actually had a client receive a DAT in serious felony sexual abuse charge with a minor), most DATS are given to defendants that have allegedly comitted relatively minor, non-violent criminal offenses (i.e. Shoplifting, disorderly conduct, harrassment, Petit larceny, criminal mischief, minor property damage/vandalism and small possessions of marijuana). The decision to issue a DAT is within the sole discretion of the police and fair or not, this is a fact.
Essentially a DAT is a summons that avoids an overnight stay at the 120 precient(SI) w/a bologna sandwich and lets you go home and return to see the judge on a certain date. Make no mistake, a desk appearance ticket is a criminal arrest, but it is just not a physical arrest and should not be taken lightly. A PERMANENT CRIMINAL RECORD is at stake....
Failure to appear on the DAT return date will result in a bench warrant be issued for your physical arrest.
