Many states in this country set a dollar amount of an item that is purposefully damaged for misdemeanor and felony status for charging purposes for a crime. For example, a state in its criminal statute could declare that an item purposefully damaged by someone whose value exceeds $750.00 could impose a felony conviction upon the person who is convicted of the crime.You need to read the statute you are charged with violating and its elements. Most likely there will be a dollar amount stated as well as what conduct is improper.If you do not have a criminal defense lawyer, you should retain one. Being convicted of any crime, especially a felony is a serious matter.
