The more laws there are, the more violators.

Literal

Laws [subject-が] many-[conditional-ば] many [more-ほど], violators [also-も] become-many

The ~ば~ほど pattern — 'the more X, the more Y'. The adjective 多い takes the 連用形-conditional 多ければ + 多いほど, literally 'if many, to the degree of many'. A classic proportional-scaling structure. 違反者 = violator (違反 violation + 者 person).
