一條法律從提案始，每一步都是由政客來決定，不可能沒有政治的因素在內。提案由“民意”而定，但民意是可以由政客們操縱的。否則現在兩黨為競選連篇累牘的廣告就都是白花錢了。
加之司法係統的執法人，比如法官，檢察官，警察總監。。。或是由政客指定，或是民選，無一不包含政治因素。
所以律師是法製社會不可缺少的職業之一，可以起一定的政法平衡作用。
How Are Laws Made? http://www.house.gov/content/learn/legislative_process/
Laws begin as ideas. First, a representative sponsors a bill. The bill is then assigned to a committee for study. If released by the committee, the bill is put on a calendar to be voted on, debated or amended. If the bill passes by simple majority (218 of 435), the bill moves to the Senate. In the Senate, the bill is assigned to another committee and, if released, debated and voted on. Again, a simple majority (51 of 100) passes the bill. Finally, a conference committee made of House and Senate members works out any differences between the House and Senate versions of the bill. The resulting bill returns to the House and Senate for final approval. The Government Printing Office prints the revised bill in a process called enrolling. The President has 10 days to sign or veto the enrolled bill.
