It would be presumptuos, on my side, to doubt about such an operation, that I suppose (am I right?) was supported by warrant for arrest by a magistrate, but let me say that it isn't so eayy to understand the crimes that this guy would have committed.
If the charges on Damra are only those exposed in the article, a doubt has to be legitimate.
In fact, to have been told having broken the siege of the Mukata to bring "rice and food" to the besieged, or to have been "watched by many" to launch a missile (the only missile!) during the prolonged clashes at the time of Defensive Shield operation, are - I beg your pardon - ridiculous.
And the other charge (involvment "with planning and supplying weapons for terror attacks to Fatah members": perhaps more correctly to be read: "supplying weapons to Fatah member for terror attacks"), is very faint and I guess it would easily extended, on the same basis, against a large majority of Palestinians (let's try to say 80%), with or without the command of Arafat (who cannot be heard on this, obviously).
So, the first impression to an uninvolved (and possibly unbiased) person like me, is that this is another step toward nowhere, at the time when a bit of political wisdom would be the only way to reach a reasonable goal for Israelis still more than for Palestinians.
Please, don't condemn me for the frankness.
