The gun grabbers may have made a huge tactical mistake.
In December of this year the SCOTUS will hear arguments in New York State Rifle & Pistol Association Inc. v. City of New York, New York.
Gun grabbers successfully petitioned NYC to write some highly restrictive gun laws. They prevailed at the District and the Appellate levels. Then in January of this year the SCOTUS agreed to hear the case. The same gun grabbing lobbyist then convinced the city to rewrite the laws and relax them for fear that a now conservative leaning Court would not only declare the law unconstitutional, but perhaps go farther and write case law rolling back other restrictive initiatives.
Once the new law was passed NYC asked the court to render the case moot. Instead, the Court basically told them to pound sand and that they would decide whether or not the case is moot.
