David Merkatz, author of the bestseller “Wrongly Charged: A Look At The Legal System,” speaks from experience. He and two other locksmiths were wrongly charged with money laundering and other major felonies. His long, winding, expensive road trip through the legal system was an eye-opening nightmare. Before his arrest, he built up and then sold three locksmith businesses. He also became a licensed stockbroker and a professional options trader. His website is www.wronglycharged.com.
