Phil, confidence tricks are often a ploy used by clever individuals to take other folks money. It's fraud, and it's against the law here in the United States. Those who commit fraud are subject to the law. Those that unknowingly buy into, purchase from, or deal with con-artists like this aren't at fault. They were taken advantage of and they have every right to complain. (A reasonable individual would assume these "victims" would learn their lesson and move on--but that's not always the case, sadly.)
It doesn't matter if the person being taken advantage of is a nursing home resident or a penny stock investor. Sure the risks associated with investing in penny stocks are greater than having some unscrupulous "nursing home employee" tricking some poor nursing home resident into giving him/her their cash---but it still boils down to FRAUD.
Folks get taken advantage of daily. Many times these con-artists get away with it. But those who get caught will face justice.
