Actually, most people care little about occasional shootings and such - it just confirms the negative image they already have of muslims.
The cause of the negative image is more formed by day to day annoyances, like having your purse stolen by a muslim, being sexually harassed by groups of muslims, being shoved aside in the supermarket because the muslim does not wish to wait in line etc. etc.
It is of course a minority of muslims who does this - but such day to day occurences tend to leave a negative impression - especially if one has no other dealings with muslims. Then turn on the tv and see this type of news - and the conclusion is formed.
