Wait a sec, that sentence also includes time the guy got for stabbing four police officers and failing to register as a sex offender.
Penalty for failing to register as a sex offender in PA is 2 to 5 years, depending on the nature of the underlying offense.
On the other hand thanks to this glittering assortment of Democrat Dimwits, killing a police dog in Pennsylvania is now a Second Degree Felony carrying at least a 10 year sentence.
