A ban on the sale and use of Class-C fireworks remains in effect -- at least through tomorrow -- in Shreveport, Bossier City, and most of Bossier Parish. But Shreveport Fire Chief Brian Crawford says there have been instances of people violating that ban. With that in mind, the Shreveport Fire Department has set up a number to call to report fireworks violations.  It's 675-2151.  You can also call the Shreveport Police Department's non-emergency numbers -- 673-7300 or 673-BLUE -- to report violations.  Those not adhering to the ban face a fine of up to 500 dollars, up to 60 days in prison, or both.
