Hence why we have LAW ENFORCEMENT to implement such laws. Police won't refuse to follow a law JUST BECAUSE citizens find it unconstitutional, they have a duty to enforce laws, and Nuremburg excuse or not, its what they will do regardless show they feel about it.
if i might inquire which laws, federal, state, or a community's ordinances ?
sooooo...feds have a long time federal mandate on the books, oh let us say the use of, possession of, marijuana is illegal on the federal stage, yet which several states have 'legalized' their citizens to use possession of and 'personal use' marijuana'!
and in the basic theme of this forum, there is no specific federal mandate prohibiting firearm ownership (notwithstanding and understand ~ age criteria, DV issues, Illegal substance usage, or MH constraints on firearm ownership) additionally (nor do i care to entertain those that throw 2A tirades into their reading of my post); several states have mitigated this federal lack of federal prohibition into their own hands with the passage state laws impeding, in some instances severely restricting their citizens from purchase of and carrying of personal firearms based on some power and control manic opinion their legislative
folk may believe in.
in the first example w/use of marijuana, any of this country's citizens can visit the state where it is legal and toke up without any fear of reprisal from the Feds; however, have a firearm while driving thorough say MD where LE's are rumored to regularly cam vehicle's license plates, checking immediately via computer, if the driver has a legal state approved permission to have a firearm.
which LEs are obliged to enforce the LAWs and which LAWs should they enforce and should the nice LEs put the agency's profit center mentality in their judgement criteria to enforce the LAW?
finally OP please consider public duty doctrine concepts...
