> Jewish land acquisition in Palestine before 1948 was often through legal purchases from Arab landowners.
Sometimes the mob wants to buy up real estate. And if people are willing to sell, it's just a transaction with varying shades of exploitation (knowing that it will be worth more when they resell).
But if those people don't want to sell, the mob doesn't just offer larger sums. There are then elements of intimidation. Strange cars drive past your home at night. You see big ugly men staring at you in a menacing fashion when you're out in public, then they wave and walk away. Bricks through windows. Anonymous threats of grave harm or murder. The escalation is constant. Anyone who sells at that point knows better than to start blabbing that they did so only because their lives were in danger... the people who extorted them don't much like being in the news even after the fact.
But that's the mob. I'm sure it was different in the first half of the 20th century in the place now known as Israel.
