OMG! Were they shooting them? In my city it is illegal to shoot a bb gun inside city limits and i have called the police on neighbor boys! Is your ex a cop? Seems he would be concerned with gun play in his house! I would be freaking out. I think I would call my lawyer and talk to her because that seems like child endangerment. I might call the police too. Or, CPS and ask them what to do, thought I don't know if i would be excited to tie up my own kid with cps. I think I might call the police.
