So I have a lexis Nexis subscription. I did a little bit of legal research on home defense precedent in Arkansas.
First of all:
"The defense of justification, including the use of deadly physical force, is statutorily based in Arkansas. Ark. Code Ann. § 5-2-607(a) (Repl. 2006). This chapter defines a "dwelling" as "an enclosed space that is used or intended to be used as a human habitation, home, or residence on a temporary or permanent basis[.]" Ark. Code Ann. § 5-2-601(3) (Repl. 2006). Arkansas case law supports the conclusion that unenclosed porches are not considered to be part of a dwelling for the defense of justification. Anderson v. State, 353 Ark. 384, 108 S.W.3d 592 (2003), citing Hopes v. State, 294 Ark. 319, 742 S.W.2d 561 (198

"
Johnson v. State, No. CR 06-993, 2007 Ark. LEXIS 250, at *6 (Apr. 12, 2007)
In the picture Boogie clearly steps out of his house with the gun. Even if he had shot Frank he would be fucked. It also does not help that shooting a warning shot is material proof that Boogie didn't actually think he was in danger of death of serious harm.
Secondly Arkansas does not appear to have a "Negligent discharge of a firearm" statute. They only have "Negligent discharge of a firearm from a vehicle" and "negligent discharge of a firearm while hunting." There was bill to add it in 2007 that was withdrawn. That being said there could still be a municipal statute that criminalizes it. Unfortunately despite looking into the Fayetteville city website I could not find any relevant code. However Simultaneous ownership of guns and drugs is a charge, although I suppose it technically isn't boogie's gun.
