Googling "abortion us protests violence" returns some links - of course mostly MSM, some summaries. Pick one and distract the amount you deem necessary for that source ;-)

Not wanting to offer german articles, at least one in english and not from the states:
https://www.theguardian.com/world/2016/apr/05/abortion-providers-violence-death-threats-planned-parenthood
While most of the items were threats, a shooting/killing reference (albeit first in 6 years) is mentioned.
