This is a great ruling - notice that with the exception of Stevens, even the liberals and pro-abortion judges *still* ruled for the pro-lifers. Thank you, God.
If they had ruled otherwise the ruling would have bit the Left right on the rear end. If RICO suits were permitted against people who do not have a direct financial stake in picketing outside a business, then PETA and all sorts of other leftie groups would have been just as vulnerable as right to life groups.
That fact probably explains why the liberal justices saw fit to rule based on the Constitution rather than ideology.
