The title comes from the leader of Saoradh, a political party that reflects New IRA thinking and their statement:
A republican volunteer attempted to defend people from the PSNI/RUC. Tragically a young journalist, Lyra McKee, was killed accidentally.
In response to the murder:
The murder of this young woman is a human tragedy for her family, but it is also an attack on all the people of this community, an attack on our peace process and an attack on the Good Friday agreement,” said Sinn Féin’s deputy leader, Michelle O’Neill.

Just whether a "backlash" from the local community will happen or have an effect is a moot point.
