The US is a country based on tweaking the law just so much that you can get away with it 99% of the time. This country has more attorneys/capita than any other developed nation. If things were done according to the law, 1/2 of them would be out of work (the law says that a rapist should spend 15-->life in prison. In reality he is allowed to plead to disorderly conduct and spit his victim in the face on the way out of the courtroom)
Whatever you mention are not "tweaking laws", but most times it's due following reasons:
1. In some occasions prosecutors are not competent enough. On the other hand defence attornies are more competent (hence more powerful). Good examples are OJ Simpson, Kobe Byrant cases.
2. In criminal court, it's "innocent until proven guilty beyond reasonable doubt". Thay's the way law is. In many cases it's not possible to prove beyond resonable doubt, because court is a court.
It's not a time-machine to verify every possible items/incident of the past. That's the limitation of court and that is how court should be seen. Sometimes court (hence law) works, sometime does not.
Due to point 2, in many cases it's not very easy to show a person guilty of a crime. In many rape cases it becomes he-says-she-says story in court (because there is no witness). Kobe Bryant case is perfect example. Prosecutors also understand that and that's why they go for much lesser punishment (or sometimes withdrawing the case alltogether).
Are you complaining that why an lawyer is defending a rapist? Because that's their job to defend client
zealously. That's not "tweaking laws" but following law in correct manner. One party wins in court and other party loses. In many occasions it's not fair, but that's the way law is. Again, it's not tweaking laws, but an unfair side of man-made imperfect legal system.
There are cases where defence lawyers are successful to defend a guilty persons, but on other other hand there are innocent people who are in death row because their defence lawyers were sleeping in court. So just seeing on side may not give you right picture of legal world.
Comparing number of lawyers with other country is absurd because every country has different career oppotunities. Legal infrastructures are different, method of excercizing laws are different. Having less lawyers does not make a country's law and order better - but just opposite.
