Too many or too few rights

Through the subjects covered in my government class I have come to realize that as Americans, we have entirely too few rights. Sure the constitution and all the amendments cover us or catch us like the safety net it's supposed to be, but reviewing many cases the supreme court makes so many ruling around the amendments just to protect the public. This means that we are horribly overwhelmed by the chinks in our proverbial armor, letting us be subjugated to illegal searches or false accusations. Like the probable cause cases where the man was falsely accused and then illegally searched because the police dog smelt drugs, Americans should have the right to defend themselves on the spot. Also the case where the group of youths were smoking some pot and could be charged for that but they should not have had their vehicle searched, the government run juggernauts meant to protect are at play shoving their superiority in our powerless faces. The US population needs more rights or these atrocities will continue, I'm not saying smoking weed is okay, I'm saying that we should be able to say if something is right or wrong.
