Luigi Mangione lawyer says arrest flaws invalidate evidence – but will it work?

Pennsylvania attorney for suspect in UnitedHealthcare CEO Brian Thompson shooting claims police violated his client's constitutional rights in arrest

Following Luigi Mangione's arrest in the brazen killing of UnitedHealthcare CEO Brian Thompson, authorities in the US heralded his capture as good old-fashioned police work" that brought an end to a manhunt that had stunned America and the world.

It had been a period of high drama and blanket media coverage. In the days that passed since Thompson was fatally shot on a Manhattan sidewalk by an unknown assailant on 4 December, police tracked down surveillance footage allegedly revealing the still-unidentified Mangione's face and widely distributed a now notorious still of him appearing to smile at a hostel, all in an attempt to find the fugitive.
