I would say it is false that someone killed a service man. 4 people died (https://en.wikipedia.org/wiki/January_6_United_States_Capitol_attack) related to the riots. 1 rioter shot by police, 1 rioter died because of overdosing drugs, 2 rally participants died from natural causes, Four police officers killed themself later and one police officer died of a stroke. So the death are not easily linkable to the riots themself. The only one would be the rioter that got shot by police. 174 police officers were injured. 15 were hospitalized. Those most definitly were directly caused by the rioters. Rioters went to the capitol freely to attack. Every single one of them could have just stayed at home. So rioters were definitly the active part of this conflict. Police has the job to stop people from entering the capitol, when someone is not allowed to intrude. And no they do not deserve to be pardoned. (opinion) They just were pardoned. (fact)
