Narrative:

After being cleared to land a helicopter requested to hover taxi for a south bound departure. Tower said 'cleared to taxi hold short of runway 7 for landing traffic.' we were short final. The helicopter then told tower we need a south bound departure as soon as possible. At 200-100 ft during landing the tower said helicopter do you have landing traffic in sight? He said yes then tower cleared him to cross our runway. We were all shocked when the helicopter crossed when we were 100-flare. It is my opinion that if we had to do a go-around that could have been a potential air hazard. After landing I phoned the tower and asked if I could come up and say hi. The tower said sure come on up. When I got into the tower the tower guys were really cool and I politely said I noticed you cleared the heli to cross when we were on short final. The tower guy said yeah. He said he had you in sight and normally doesn't go that way. I said I understand it was a medical emergency. 'Medavac' well we are not used to that so I just wanted to come up and say hi. It was a medical helicopter that requested priority. Maybe wait [until] we landed to clear the helicopter across the runway.
