President Donald Trump on Thursday told troops deploying to the border they could shoot migrants who might throw rocks at them.
[Editors note: President Trump appeared to walk back his remarks about rules of engagement on Friday.]
But what troops will actually be able to do — or should do — is tightly governed.
Experts on domestic military deployments said the president’s words would not offer protection to forces in the case that troops fire upon a migrant and cautioned that troops must know and follow the rules of engagement specific to this unique deployment.
