Continuity mistake: When the thief tries to steal the truck and the owner is beating him up, the passenger window behind the driver breaks. When his daughter later gets into the truck, very briefly the window is not broken. Then the next shot shows her in the truck, the window is broken again.
Continuity mistake: The same flashback of Roslyn Jareau giving her necklace to JJ is shown twice, but their dialogue is slightly different the second time.
Continuity mistake: Reid moves his gun to his side after the militia tell him he is begging for someone to take it. You can see it after they send Morgan to the bar. One second it's on his side, the next second it's back in front off his hip like always. (00:23:15)
Continuity mistake: While George Foyet is stabbing Agent Hotchner, the knife is extending from the handle. The blood is at the top of the blade, and as he removes it, the blood moves to the bottom of the blade, while the top remains clean.
Continuity mistake: When Reid is asked if he plays ball, the way he holds the football changes between shots. In one shot he holds it in 2 hands and in another he holds it in one hand. (00:14:30)
Continuity mistake: When Morgan finds the Glock 19, his grip on the clip changes between angles. (00:14:30)

Compulsion - S1-E2
Continuity mistake: When Gideon profiles the campus patroler, the necklace's position changes on his shirt between the close and long shot. (00:17:40)
Continuity mistake: When Wallace brings the snake home he takes it out of the tank and holds it. Between the constant shot changes the snake's position changes entirely.
Continuity mistake: At the start we see Spencer explaining to Gideon about the Boston Strangler, his orange shirt is untucked at the front with both sides of his shirt being visible. Camera shows Gideon walking off and now only 1 side of his shirt is untucked. (00:05:10)
Continuity mistake: When the team visit the home of Marcie Mitchell, the older boy takes the baby to another room. The baby is crying, then as they are in shot walking through the door the baby is looking around and smiling, and as the door shuts we hear crying again. (00:11:20)
Continuity mistake: At the end of the episode, the team and their SUVs are spike stripped and then hit by a semi. When the team is shown in the SUVs and when the SUVs are shown hitting the sticks, the SUVs are eleventh generation Suburbans, but when the semi is shown hitting them, they're ninth generation, at least nine years older.
Continuity mistake: They keep showing the aerial view of one type of jet (such as Gulfstream 100 with its rectangular windows), but the inside shots are always in a "heavy" Gulfstream (such as Gulfstream IV or Gulfstream V, which have round windows). Also, the tail numbers (the N-numbers written on the engine) are always different in the aerial views. Some end with GV, some with SP etc.
Continuity mistake: When Reid is talking there's a big crack at the top of the window that might be a problem since they're supposed to be flying. Then a few seconds later they cut back to him and it's filled with putty. (00:05:00 - 00:06:00)
Continuity mistake: After Emily shoots the unsub in the head and he falls on the bed, the gun falls beside him. A second later they show her walking over to his body to remove the gun from his hand. (00:51:00)
Continuity mistake: When Garcia accesses the bank's page online Prentiss gives her the account number login, 1552 9384 6729, and we see Garcia typing it correctly on the screen with the password, but when it cuts to the account's page showing deposit and balance, we see in the balance box the account number's last four digits are 7629, not 6729.
Protection - S10-E22
Continuity mistake: In the final stand off, Daniel fires 16 rounds through the door/wall at the team. We've already been told his gun only holds 14 bullets. Not to mention without reloading he fires a few more bullets shortly afterwards.
Continuity mistake: The clock on the bomb's secondary timer doesn't match with reality while Prentiss is trying to defuse it - going from 15 seconds to 10 too slowly, then skipping the final few seconds so it can end on 1 second remaining.
Chosen answer: Black SUVs are common police, military and dignitary vehicles around the world. It is not too much to assume they could be rented or owned by the police forces in the areas.

Other people have explained it but fore more information, federal cars would most likely be brought to the airport from the nearest agency, so they can drive out to their locations especially in rural situations.
