Is International Humanitarian Law strong enough to make good reporting?

Is international humanitarian law strong enough to make 'good reporting' feasible in war zones?

First of all, we should have some ideas of what International Humanitarian Law is? The International Humanitarian Law forms a major part of international law.

Here is the picture which indicates the role of IHL within international laws

In 1864 Geneva Convention laid the foundations for contemporary humanitarian law. It was chiefly characterized by: 1). standing written rules of universal scope to protect the victims of conflicts;

2). its multilateral nature, open to all States; 3). the obligation to extend care without discrimination to wounded and sick military personnel;

4). respect for and marking of medical personnel, transports and equipment using an emblem (red cross on a
white background).

And gradually the IHL has evolved in different stages, most notably known as the four Geneva convention of 1949 and additional protocol I of 1977.
These treaties are also the basis for the International Committee of the Red Cross(ICRC) to carry out their duties.
