Will the Chardak Campaign Be Ended Due to the Law?

A short while ago it seemed like the "Chardak" campaign was over. It had gone on a long hiatus, and then there was a court case against somebody who had been exposed as the original artist and owner of the artwork who was being sued for inciting violence.

Recently, though, some new "chardak" posters have gone up in various areas. In my impression, the art-work on the new signs looks different than the originals - it is not as good or effective, and, the new posters have not been spread as widely as they had been previously. I don't know why, but I suspect that it is now different people behind it than those who were originally there.
Anyways, a law is being proposed by which verbally or physically attacking a haredi soldier regarding his service will be punishable by 6 months in prison and a 250,000 NIS fine.
Yaakov Vieder, head of the Haredi branch of the Likud, has initiated the law proposal and has garnered support for it from MKs from all the parties in Knesset.
As explained in the law proposal, fringe groups have in recent years selected haredi soldiers as an easy target for their hatred, and as targets for verbal and physical attacks, knowing no significant criminal processes would be initiated against them. This law will send a unilateral message of the IDF standing strongly beside its soldiers and delineate clearly the balance between freedom of expression and incitement.
The Attorney General, however, let Vieder know that there is no need for such a law proposal - there is already a law against attacking or insulting soldiers and State employees, and haredi soldiers are included in this.

2 questions:
1. if the law already protects haredi soldiers just like any other, why has little or nothing been done to that effect?
2. what happens if they don't know who is behind the insults and incitement, such as with this anonymous chardak campaign? How do they know who to punish? How does this new law (if it will pass) or the old law help protect the soldiers in the situation of the chardak campaign?
