Hmm.. a few things I disagree with here -
- They obviously did have a warrant, or else they wouldn't have come to search the house. They couldn't have broke down the door without a warrant.
-Just because she has Cancer doesn't mean anything. For all they knew, Tim was missing and a person living at this house was connected the a missing person. In these cases, (as we saw) many of the suspects are armed, so they have to take every precaution.
- You mentioned MS was under surveillance, so they should have known he wasn't there. But he was also under surveillance at the time he "buried" the gun, so obviously they weren't able to track him 24/7 and they may not have been 100% sure where he was at the time.
-Finally, yes she does have other children. And herself and these other children made a decision to allow a drug dealer and thief to live in their house. You think she had no idea that her son dealt drugs? He had no job, and no way to support himself. She could have made a decision to kick him out of the house due to his illegal activities and non of this would have been an issue for her.
Generally I am not one to support the police in these sort of things, and I can say I have had some bad run in myself with the Halton Police. But lets be real here, if it was your husband who was missing would you have any issues with the police searching the home they lived in?
