A local lawmaker is calling on his colleagues to take up a bill he introduced last session that would limit the number of firearms an individual may purchase within a 30-day period.  Ridgefield Senator Will Haskell says he plans to advocate for a similar bill to be considered by the Judiciary Committee.  He notes that California, New Jersey and Maryland have limits.  In a nationwide study by the Giffords Center, roughly 65 percent of those surveyed support a one-per-month limit on gun purchases.
