I'm not sure it's alpha vs. non-alpha here.
I think alpha males are bold. They are inclined to action, and to being assertive. Whether the law can help them or not (and possibly whether the law is even on their side) is less of a concern than driving the action forward.
On the other hand, men who go to the police when they feel they are wronged could be one of two kinds, neither of which seem exclusively "alpha" to me. They could simply be civilized, wishing to avail themselves of peaceful means of addressing conflicts. I can see alphas and non-alphas doing that. Or, they could just be Kevins (the female equivalent of Karens.) That definitely does not strike me as being "alpha."
