Ignorance of the law is no excuse. Officer Michael Doughertys ignorance does not excuse his reckless endangerment, assault with a deadly weapon, his childish and unprofessional disorderly  conduct, his unlawful arrest and abuse of process. What Sgt Michael Dougherty did was very dangerous, reckless, negligent and stupid. Sgt Michael Dougherty recklessly endangered lives. Sgt Dougherty committed aggravated assault, threatened a peaceful lawful citizen with deadly force, acted in an extremely unprofessional, childish and emotional  manner, and lied (but thankfully was caught on tape). Thankfully the victim, Mark Firorino, remained calm, professional, orderly and rational and was able to deescalate the reckless situation Officer Dougherty created. Officer Michael Dougherty should suffer serious discipline and if he should remain on the Philadelphia police force at all, Sgt. Michael Dougherty should never be permitted to carry a firearm while on duty again. Officer Michael Doughertys reckess, dangerous, unlawful and disorderly conduct will likely and rightfully cost the City of Philadephia money time and resources.
