There's 84 total grenade launchers in the data set, if you are curious. Florida took twice as many as CA (36 to 18) and the rest of the states with them are under 10. Why Florida needs so many is another question...
Also interestingly, Montgomery got all 9 of AL's grenade launchers, more than Sacramento or LA took.
edit: actually, this data is wrong because I only used the first page, didn't even see the other 3....
There was a big thing made about it in Bergen County, NJ when it was first reported that they had received one. The police basically said they had no use for it and couldn't even image a reason to use it.
