In-plane resistivity, Hall coefficient, and magnetoresistance are measured in a series of high-quality Bi2Sr_2\ensuremath-xLaxCuO6 crystals with various carrier concentrations, from underdoped to overdoped. It is found that the temperature dependence of the cotangent of the Hall angle obeys a power law T^\ensuremathα with \ensuremathα systematically decreasing with increasing carriers. While the observed power-law behavior supports the scattering-time separation, the universality of the Fermi-liquid-like T2 dependence of the Hall scattering rate is seriously questioned.
