"Zakat HaEemahot" means
"The Cry of the Mothers," and the mothers, fathers, sisters, brothers, family & friends of young Israelis who have been killed by random violence such as murders, car thefts gone wrong, being in the wrong place at the wrong time, etc. are camped out in front of Prime Minister Ehud Olmert's residence in Rehavia, trying to get him to pay attention to their plight.
This group is advocating for a change in procedures for the "24 Hour Law," meaning police won't open a file or an investigation on a missing person until they've been missing 24 hours.
The families sit on chairs behind pictures of four young Israelis whose lives might have been saved if their frantic families who had called police about their missing children would have been able to open an investigation before their child had been missing 24 hours.

Unfortunately, Prime Minister Olmert was too busy giving away land to Fatah (and their almost newly reconciled ex-best-friends Hamas, who are just about to re-join the PA government after their recent spat in Gaza that killed hundreds of their own) and freeing terrorists to pay any attention to "the cry of the mothers."
