Lewinski is also a much sought-after expert witness whenever a law enforcement officer is put on trial for the use of excessive force in the line of duty. Lewinski founded a company called Force Science LTD and has trained tens of thousands of law enforcement officers nationwide in recent years.

A problem just then in its infancy but in the spotlight after a string of police killings of Blacks in Ferguson, Mo. and elsewhere. Social media and the proliferation of smart-phones was beginning to have a profound influence on how law enforcement of citizens is handled.
