Re-posting from Google Plus: When the suspect in a violent crime is 18 or 19 (a legal adult) it is very irritating when he (usually a he) is referred to as a "teenager." That may be factually correct, but it is misleading and often intentionally dishonest. The suspect is a man, not a teenager.
Also, someone who is between 18 and 20 and drinking illegally is not a "minor." He or she is underage. There is a big difference.
