Unscrupulous, unprincipled refer to lack of moral standards or conscience to guide one's conduct. The unscrupulous person is without scruples of conscience, and disregards, or has contempt for, laws of right or justice with which he or she is perfectly well acquainted, and which should restrain his or her actions: unscrupulous in methods of making money, in taking advantage of the unfortunate.
New York City has an annual Pulaski Day Parade and Grand Rapids, Michigan holds Pulaski Days at this time. Some areas with large Polish-American populations instead celebrate Casimir Pulaski Day on the first Monday of every March, marking Pulaski's March 4, 1746 birth. Wisconsin, Illinois, Kentucky and Indiana have state recognition of this holiday, which is particularly popular in Chicago and Milwaukee.
The State of Illinois has celebrated Casimir Pulaski Day on the first Monday of March since 1977, no doubt due to the large Polish population of the city of Chicago; Pulaski Road, one of the city's major arteries, is named after him.
