In this day and age so many people are frustrated because there are so many wrongs in this world and they cant do anything about them. The news fills people with anger and when they see someone that in their mind is "breaking the law" they feel that they are justified in saying something. Nevermind that they are jumping to conclusions, they go off questioning and hollering.
Of course there is fraud, there is fraud in a lot of things. If you are so sure, call the Police. Let them handle it. Another poster says dont be offended if someone questions you. HORSE HOCKEY! If someone tries to harass or intimidate someone by hollering and accusing, Im going to get offended. People need to chill.
