johnny - You appear to be taking a popular position, which is actually not logical.
Under the terms of your OP, police neglect domestic crime to concentrate on this high-profile incident, therefore if they concentrated less on the high profile incident, they could concentrate more on domestic crime.
The failure of logic is simple - the police focus on both, it's just that the current high-profile incident is just that - high profile.
It's easy to be lured into the notion that something that gains more media exposure is receiving more attention because it is perceived to me 'more important', but this is not in fact the case.
Both are receiving appropriate attention from the government and the police, it's simply that one is more newsworthy than the other.
