"Red flag" rules

Discuss the Constitutional debates involved in bans on semi-automatic rifles
and "red flag" rules. Define and defend your own positions on those debates.In your
understanding of the 2nd Amendment (following DC v. Heller) what restrictions (if any)
may be placed on firearms?. What standard is required to place those limits
(intermediate scrutiny? strict scrutiny?) Would a ban on semi-automatic rifles meet those
standards? What constitutional questions are suggested by "red flag rules."? Can a "red
flag law" be defined to meet those concerns? If so describe it.
