Final answer:
Asking an individual if they are over 21 is not an effective tactic for identifying falsified identification. Removing the ID from the wallet and comparing both the picture and signature to the individual are more effective methods. The larger debate on voter ID laws also highlights the potential barriers these laws create for certain groups of people.
Step-by-step explanation:
As for tactics that may not be effective in identifying falsified identification, asking the individual if he is over 21 is not generally considered a reliable method. Two other tactics are more likely to be useful: removing the ID from the wallet, which allows a closer examination of the ID for any tampering or irregularities and comparing the signature of the person with the one on the ID to check for consistency.
Crucially, directly comparing the picture on the ID to the person presenting it is another active tactic since physical resemblance can be a strong indicator of the ID's authenticity.
However, related to the broader conversation on ID laws, especially voter ID laws, it is pertinent to consider their implications. Proponents argue they prevent fraud, while opponents claim they can act as a barrier to voting, citing the financial and logistical challenges that obtaining such identification presents, especially for the elderly, minorities, and low-income individuals. Furthermore, obtaining necessary documentation, such as birth certificates, can impose a financial barrier to the ballot box.
