1. One problem with mandatory arrest policies in domestic violence cases is that both parties may allege that the other was the aggressor, requiring the police to arrest both parties, including an innocent victim who may have been acting in self-defense. Without a law or policy limiting the officer’s duties under the mandatory arrest law in the dual arrest context, victim complaints to the police will be deterred by fear of personal arrest, contrary to the purpose of the mandatory arrest law. Hence, states have adopted an amendment to the mandatory arrest law authorizing the officer to arrest only the primary aggressor. A corollary amendment often provides an incentive to exercise judgment in dual arrest situations, by requiring the officer to fully explain why a dual arrest was made. Because the problem of dual arrests is exacerbated by the court’s issuance of mutual orders of protection to both parties, many state laws contain provisions limiting the authority of the court to issue mutual orders of protection. See Mary O’Brien, Mutual Restraining Orders in Domestic Violence Civil Cases, 30 Clearinghouse Rev. 231 (1996). State laws setting forth "dual arrest" or "primary aggressor" guidelines for police to follow in making arrests include Ala. Code [new], Ala Acts 2000, Act 266, 5; Alaska Stat. 18.65.530 (b); Ariz. Rev. Stat. Ann. 13-3601 (B) (self defense is not an act of domestic violence); Col. Rev. Stat. 18-6-803.6 (2); Conn. Gen. Stat. Ann. 46b-38b (b); Fla. Stat. Ann. 741.29 (4), 901.15 (7) (public policy to discourage dual arrest), 943.171 (1) (training in dual arrests); Ga. Code Ann. 17-4-20.1 (b); Iowa Code Ann. 236.12 (3); Md. Code Ann. art 27 594B (d)(2) (self defense consideration); Mass. Gen. Laws Ann. ch. 209A 6 (7) (special report required); Mich. Stat. Ann. 28.1274(3) (3)(b)(ii); Mo. Rev. Stat. 455.085 (3); Mont. Code Ann. 46-6-311 (2)(b); Nev. Rev. Stat. 171.137 (2); N.H. Rev. Stat. Ann. 173-B:9; N.J. Stat. Ann. 2C:25-21 (comparison required); N.Y. Crim. Proc. Law 140.10 (4)(c); N.D. Cent.

A number of other states (and some of those with dual arrest laws) also have statutory provisions that tell police not to discourage reporting of domestic violence by threatening arrest of the person making a complaint. See, e.g., Conn. Gen. Stat. Ann. 46b-38b (b).
