First off this is only relevant to Defense Intelligence; it doesn't cover deploying the 82nd airborne to shoot trump voters.
3.3 starts with "subject to paragraph 3.1" which describes the already-existing laws they are required to follow, such as Posse Comitatus. 3.3 also says anything that might potentially be lethal requires SecDef approval.
All of this is further restricted by DOD policy 5210.56 which has what seem to me are extremely sensible rules regarding use of force during investigative / law enforcement duties. https://www.esd.whs.mil/Portals/54/Documents/DD/issuances/dodd/521056p.PDF?ver=PIvIb3eht0obgolnD0UCEw%3d%3d
This document is replacing the previous policy from 1982 under president Reagan which is very similar but with less detail. https://www.esd.whs.mil/Portals/54/Documents/DD/issuances/dodm/524001r.pdf
None of this looks unusual or inflammatory to me. Would you rather the DOD NOT have written policies limiting the use of force?
