text: what does "criminal summons issued" mean?   it is an order by the court of jurisdiction to appear before that court at the date and time specified.  it is sent instead of having a law enforcement officer arrest you.  by showing up as ordered it will look better for you and will save you a day or two in the county jail.   however, if you fail to appear an arrest warrant will be issued and you will go to jail, possibly needing a bail bond to get released.  suggestion.......show up!
