There are technical limitations to archiving a web site, and as a consequence, it is possible for opposing parties in litigation to misuse the results provided by web site archives. This problem can be exacerbated by the practice of submitting screen shots of web pages in complaints, answers, or expert witness reports, when the underlying links are not exposed and therefore, can contain errors. For example, archives such as the Wayback Machine do not fill out forms and therefore, do not include the contents of non-RESTful e-commerce databases in their archives.

First, the Manchus had entered "China proper" because Dorgon responded decisively to Wu Sangui's appeal. Then, after capturing Beijing, instead of sacking the city as the rebels had done, Dorgon insisted, over the protests of other Manchu princes, on making it the dynastic capital and reappointing most Ming officials. Choosing Beijing as the capital had not been a straightforward decision, since no major Chinese dynasty had directly taken over its immediate predecessor's capital. Keeping the Ming capital and bureaucracy intact helped quickly stabilize the regime and sped up the conquest of the rest of the country. However, not all of Dorgon's policies were equally popular nor easily implemented.
Why did Dorgon keep Beijing as his capital?

Pharmaceutical companies whose products are used in the three-drug cocktails for lethal injections are predominantly European, and they have strenuously objected to the use of their drugs for executions and taken steps to prevent their use. For example, Hospira, the sole American manufacturer of sodium thiopental, the critical anesthetic in the three-drug cocktail, announced in 2011 that it would no longer manufacture the drug for the American market, in part for ethical reasons and in part because its transfer of sodium thiopental manufacturing to Italy would subject it to the European Union's Torture Regulation, which forbids the use of any product manufactured within the Union for torture (as execution by lethal injection is considered by the Regulation). Since the drug manufacturers began taking these steps and the EU regulation ended the importation of drugs produced in Europe, the resulting shortage of execution drugs has led to or influenced decisions to impose moratoria in Arkansas, California, Kentucky, Louisiana, Mississippi, Montana, Nevada, North Carolina, and Tennessee.
