There are a lot of details about this point... Police have a bad habit of harassing populations (several riots in France were a result of policing practices such as asking everyone for an ID). It helps to contribute to send a message of unwelcomeness to people who are likely already disillusioned in the system. It's unlikely that more police could stop attacks. Maybe deal with the aftermath/manhunts better. But it sounds like more precision operations (including human intelligence) will go a lot further.
